Question

Megan evans has a coupon that saves her $1 when she buys two jars of peanut butter. the peanut butter costs $2.39 per jar. what is the final price of the two jars? $3.78 $3.98 $3.47 $3.21

Answer 1

$2.39 * 2 (jars of peanut butter) = $ 4.78. $4.78 - $1 (discount because of the coupon when buying 2 jars of peanut butter) is equal to $3.78. Therefore, the final price of the two jars is $ 3.78.

To simply put -
($2.39 * 2) - $1 = $3.78
