problem: The price of a T-shirt is $ 40. If you buy 3 t-shirts, you will get 15% discount.

question: How much do you have to pay for 3 t-shirts?

given:

the base value = $ 120

the rate = 85% (100% – 15%)

wanted: part (reduced price for 3 t-shirts)

formula:

we buy 3 t-shirts therefore 3 * $ 40,- = $ 120,-

part = base value * rate : 100

part = 120 * 85 : 100

part = $ 102

answer:

You have to pay $ 102.
