Alekssandra [29.7K]

Answer:

32.40

Step-by-step explanation:

The shirts were 40% of the regular price

The sale price of 1 shirt was

18*40% = sale price

18*.40 =7.20

He  bought 3 shirts, so multiply by 3

3 * 7.2 =21.60

He paid 21.60

The price he would have paid without the discount is

18*3 = 54

The savings is

54- 21.60 =32.40
