Question

Mikayla bought five shirts at $x three of the five came with a matching top for an additional $9 each. Write and simplify an expression that represents the total cost of her purchase

Answer 1

5x + 27

Explanation:

Since Mikayla bought five shirts each costing $x it would be 5x

->if three of the five came with a matching top for an additional $9 each, it would be 3 x 9.

therefore, the expression that represents the cost of her purchase is:

Total cost of purchase = 5x + (3 x 9)

Total cost of purchase = 5x + 27

Answer 2

The simplified expression that represents the cost of her purchase is "5x + 27"

Explanation:

Since Mikayla bought five shirts each costing $x we need to multiply the number of shirts by the cost, so 5*x, but since three of these shirts came with and additional top that costs $9 we need to take those into account. So the expression that represents the cost of her purchase is:

cost of purchase = 5*x + 3*9

cost of purchase = 5x + 27
