Question

A clothing store has the sign shown in the shop window. Pani sees the sign and wants to buy 3 shirts and 2 pairs of jeans. The cost of each shirt before the discount is $12, and the cost of each pair of jeans is $19 before the discount. Write and simplify an expression to find the amount Pani pays if a $3 discount is applied to her total

Answer 1

P=3(12)+2(19)-3

P=$71

Explanation:

Pani buys 3 shirts for $12 each. This is the expression 3(12) for the cost.

Pani also buys 2 pairs of jeans for $19 each. This is the expression 2(19) for the cost.

She pays together 3(12)+2(19) but she also gets a $3 discount subtracted from her total. So her total price P is P = 3(12)+2(19)-3.

Simplify the parenthesis first.

P=3(12)+2(19)-3

P=36+38-3

P=$71
