Answer:

Cost Expression 1.29 X 21

Step-by-step explanation:

Given, Ross is shopping for mulch that costs $1.29/cubic foot.

He bought during his first trip =16.5 cubic feet

And, he needs another cubic feet to complete his landscaping project  which is 4.5 cubic feet.

Now, we will have to find the expression which shows total cost in dollars of the mulch.

Given information,

Cost of 1 cubic foot =$1.29

And the total number of cubic feet he bought=16. 5

Extra cubic feet needed=4.5

Now,

Total cubic feet he bought=4.5+16.5=21 cubic feet

Hence, Total cost = 1.29 X 21

the total cost is $27.09
