Step-by-step explanation:

We are given that Ross is shopping for mulch that costs $1.29 per cubic feet.

He bought during his first trip =16.5 cubic feet

He need another cubic feet to complete his landscaping project =4.54

We have to find  an expression which shows total cost in dollars of the mulch.

Cost of 1 cubic feet =$1.29

Total number of cubic feet he bought=16. 5

Total cubic feet he bought=4.54+16.5=21.04 cubic feet

Total cost =

Hence, the total cost $27.1416 of the mulch.
