Question

Write an equation to represent the situation.
Mrs. Davis bought one pair of pants and two polo shirts for each of her three children. She had $3.09 left after purchasing the clothing items for her children.
Item : polo shirt pants sweater jacket
Price ($) : $9.99 $12.99 $15.99 $19.99
Let m represent the amount of money Mrs. Davis initially had to spend on each of her three children.

Answer 1

Answer:

3(m - 32.97) = 3.09

Step-by-step explanation:

She started with m money for each of the three children.

A pair of pants costs $12.99. Each polo shirt costs $9.99.

A pair of pants and 2 polo shirts cost

$12.99 + 2 * $9.99 = $12.99 + $19.98 = $32.97

For each child, she had m money and spent $32.97.

For each child, she had m - 32.97 money left.

For the three children, the amount of money left was 3(m - 32.97).

We are told that for the three children, the amount of money left is $3.09.

That means that 3(m - 32.97) must equal $3.09.

The equation is:

3(m - 32.97) = 3.09
