Answer:
32
Explanation:
normal cost of the tennis racket is $80
10% of 80 is 8 you get that buy doing 80 ÷ 10
then 8 which is ten percent × 6 (to make it 60)
8 × 6 = $48
total price - discount
80 - 48 = 32
you could also just do 8 × 4 which would give you 40 percent of the total price :)
8 x 4 = 32
