Question

Geri used coupons at the grocery store and received a discount of $40.94. Once her discount was subtracted, the final cost of her purchases was $122.80. What was the approximate percent decrease in the price of her groceries due to the coupons?

Answer 1

Price after discount = 122.80

Discount = 40.94

So, amount before discount = 122.80 + 40.94 = 163.74

$\% \: decrease \: in \: price \: = \: \frac{discount}{original \: price} \times 100$

$= \frac{40.94}{163.74} \times 100$

= 0.25 x 100

= 25%
