Problema Solution
Suppose you purchased a $60 pair of shoes that is on sale for 40% off and a $40 that is 20% off. What percent of discount did you get on the total amount?
Answer provided by our tutors
Without discount: $60 + $40 = $100
With discount: $60(1 - 0.40) + $40(1 - 0.20) = $68
x = total discount
$100(1 - x) = $68
100 - 100x = 68
100x = 32
x = 0.32
You got a 32% discount on the total amount.
