total cost, x pounds of kiwi and y pounds of cherries:

Explanation:

Step1: Calculate cost of kiwi (2.5 pounds)

Kiwi cost per pound is $4.50, so for 2.5 pounds: $4.50\times2.5 = 11.25$

Step2: Calculate cost of cherries (3 pounds)

Cherries cost per pound is $3.25, so for 3 pounds: $3.25\times3 = 9.75$
