1) Discount- What you save.

2) Sale Price- What you pay after discount.

3) Total Price- Sale Price and Taxes

How To get the Discount.

Make the percent to decimal. 25% ÷ 100= 0.25 Then,multiply the decimal to the original price.

0.25x$75=$18.75 so, the discount is $18.75

How to get the Sale Price.

Subtract the original price and the discount to get the sale price. $75-$18.75= $56.25 So, the sale price is $56.25

How to get the Total Price.

The tax is depend to which country you are. So, our tax is 12% or 0.12 or 1.12

There's two ways to get the Total Price.

1) you can multiply the Sale price and our tax which is 0.12

So, $56.25x0.12=$6.75 then Add $56.25+$6.75 and you'll get $63.

2) You can multiply the sale price and 1.12

$56.25x1.12 and you'll get $63

1st week 50% off

85 divided by 2 equals $42.50

2nd week 10% of the already reduced price

42.50 divided by 10 equals $4.25

### Kate's Pay it Forward

Part 1

Pay it forward means doing good things to other people and making a difference for their life.

Part 2

My Pay It Forward is an act of kindness to help Charry’s auntie's friend who's disabled. we did this with my partner Charry Mangaya. We decided what are we going to do. We chose this activity because we like to help (old) people with disabilities. We helped Precilla Malla, we call her tita (auntie) Malla, she's 59 years old, and she’s disabled with psoriasis arthritis and diabetes since 2003. We asked her what we can do for her. We did this act of kindness last November 13, 2011 at 11:30 A.M to 3:30 P.M.

Part 3

Our act of kindness went well. First Charry introduced me to her; we asked her "what can we do for her?”

We saw her kitchen, there's a lots of dirty dishes. So, we washed it, we cooked rice for her, we swept the floor, we cleaned her table. We saw her bedroom and she asked us is it okay to help her fold some of her clothes and we said “yes we can". We noticed that her bedroom is crowded with her things and a little bit messy; I told her that we can do some "interior designing to her bed room ". We moved some stuff, while we're cleaning up; we were talking and sharing stories like her experience when she's young. We're done at that time. We asked permission, if we can take a video and a photo to her. She approved. She was so happy when she saw her bedroom was all cleaned up. She told us that she's going to pay but we told her that it’s okay because we did this for free and she doesn't have to pay us .She's so thankful to us . She wants us to visit and to come back if we have a free time. Charry and I had so much fun . were so happy because we make her so happy and Charry and I helped each other to take pictures and videos and to help Tita Malla.

Part 4

Pay it forward is important because you share good things to others with the intension to make a difference not only to their life’s but to yourself as well .

**4. What is the percent of each number? Give you answer to the nearest hundredth.**

**Step 1**: Find out what 1/5% is as a decimal. To do this we take 1 and divide it by 5 that equals 0.2% (1 ÷ 5 = 0.2)

**Step 2**: Then find out what 0.2% is as a decimal. To do this we take 0.2 and divide it by 100, that equals 0.002. (0.2 ÷ 100 = 0.002)

**Step 3**: Then you take 0.002 and multiply that by 630. And your answer is 1.26.

~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~

**Step 1**: Find out what 7/8% is as a decimal. To do this we take 7 and divide it by 8 that equals 0.875% (7 ÷ 8 = 0.875)

**Step 2**: Then add 23 with 0.875. (23 + 0.875 = 23.875)

**Step 3**: Then find out what 23.875% is as a decimal. To do this we take 23.875 and divide it by 100, that equals 0.23875 (0.23875 ÷ 100 = 0.23875)

**Step 4**: Then you take 0.23875 and multiply that by 300. And your answer is 71.625 (0.23875 x $356.80 = 71.625)

**Step 5**: Round 71.625 to the nearest hundredth. (71.625 ≈ 71.63)

**Step 2**: Then you take 2.45 and multiply that by $356.80. And your answer is 874.16 (0.23875 x $356.80 = $874.16)

**Step 1**: Find out what 3/4% is as a decimal. To do this we take 3 and divide it by 4 that equals 0.75% (3 ÷ 4 = 0.75)

**Step 2**: Then add 68 with 0.75. (68 + 0.75 = 68.75)

**Step 3**: Then find out what 68.75% is as a decimal. To do this we take 68.75 and divide it by 100, that equals 0.6875 (68.75 ÷ 100 = 0.6875)

**Step 4**: Then you take 0.6875 and multiply that by 700. And your answer is 501.875 (0.6875 x 700 = 501.875)

**Step 5**: Round 501.875 to the nearest hundredth. (501.875 ≈ 501.875)

**Step 1**: Find out what 360% is as a decimal. To do this we take 360% and divide it by 100, that equals 3.60 (3.60 ÷ 100 = 3.60)

**Step 2**: Then you take 3.60 and multiply that by $129.95. And your answer is $467.82 (3.6 x $129.95 = $467.82)

**6. Table salt is a chemical compound of sodium and chlorine. Recommended daily intake is about 1700mg. If Canadians consume 182% of this amount on average, how much sodium is one person eating daily?**

Step 2 : Then divide 1700mg by 100 (1700 ÷ 100 = 17)

Step 3 : Then take 1% and multiply it by 182, to get 182%. (1% x 182 = 182)

Step 4: Then multiply 17mg by 182 as well. (17mg x 182 = 3094)
