c. How much does a customer pay for three memory cards if the store increases the percent of discount in part (b) by 2%?


The customer pays __

Answer 1

1. $937.5

2. 5%

3. $46.50

Explanation:

Question 1:

1. 25% of 25 is 6.25. To find how much the store paid for each memory card, we subtract 6.25 from 25 to get 18.75.

2. Now that we know how much the store paid for each memory card, all we have to do is multiply that value by 50. 18.75*50=937.5

Question 2:

1. Subtract the price from the original price. 50-47.5=2.5

2. Divide this number by the original price. 2.5/50=0.05

3. Multiply this number by 100. 0.05*100=5, so the discount was 5% off.

Question 3:

1. The percent of discount in part be was 5%, so adding 2% would equal a 7% discount.

2. 7% of 50 (the original price) is 3.5. 50-3.5=46.5, so the customer would pay $46.50
