Question

Michelle paid for 2.5 pounds of peanuts with a ten-dollar bill. She received $1.20 in change from

the cashier. What was the price, per pound, for the peanuts?
$0.48
$2.08
$3.00
$3.52

Answer 1

The price per pund for the peanuts was $3.52

Explanation:

To solve this problem we have to present as an equation and then solve what we want to calculate

x = price per pound

10 - 2.5 * x = $1.20

we clear x and then solve

- 2.5 * x =$1.20 - 10

x = ( $1.20 - 10 ) / -2.5

x = -8.8 / -2.5

x = 3.52

The price per pund for the peanuts was $3.52

Answer 2

$3.52

Explanation:

10-1.20 = 8.8 / 2.5
