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

Explanation:

Price after discount = 122.80

Discount = 40.94

So, amount before discount = 122.80 + 40.94 = 163.74

`decrease`
`in`
`price` =
`(discount)/(original price)` x 10

=
`(40.94)/(163.74) (100)`

= 0.25

= 0.25 x 100

= 25%
