Answer:
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
Answer:
5x + 27
Step-by-step 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
