Question

Tina is shopping for school clothes. She realizes that good sales can help her to get more clothes and keep within her budget. She picked out a $16.99 dress and a $12.95 skirt. The store was offering a 20% discount on the total sale. Using a proportional relationship, find the price she paid for the items.

Answer 1

$23.952, since money is always rounded up $23.96

Explanation:

the first step is to get the total value of her purchases, thus we add 16.99 + 12.95 to get 29.94

since she will receive a 20% discount that means that she will be paying 80% of the total value

next we set up the ratio as follows:

portion paid / total = x/29.94 = 80/100

solving the ratio gives you 23.952
