Answer 1

• The difference of 15 and 4 times a number

4a - 15

• I want to buy 4 tickets to go to Disney World. They are currently on sale for with a 12% discount.

100% representate the original cost of tikets,

100% = 100/100 = 1

12% discont:

12% = 12/100 = 0.12

1 - 0.12 = 0.88

0.88

then the expressión is:

4*0,88d

=3.52 d

d = original cost of each ticket
