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

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

Step-by-step 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
