Answer
Find out the price of the shoes last week .
To prove
As given
The price of a pair of shoes is $52.
The price is 15% lower than last week.
15 % is written in the decimal form
= 0.15
15 % of the price of shoes = 0.15 × 52
= 7.8
The price of the shoes last week = price of a pair of shoes this week + 15 % of the price of shoes
= 52 + 7.8
= $ 59.8
As
1 dollar = 100 cent
59.8 dollar = 59.8 × 100
= 5980 cent .
Therefore the price of the shoes last week is 5980 cent .
