Answer:
[tex]1.29 \times 45+1.29 \times 16.5[/tex] or [tex]1.29 (45+16.5)[/tex]
Step-by-step explanation:
Given :
Ross is shopping for mulch that costs $1.29 per cubic foot.
During his first trip to the store, he bought 16.5 cubic feet. He needs another 4.5 cubic feet to complete his landscaping project.
To Find: What expression shows the total cost in dollars of the mulch?
Solution:
Cost of 1 cubic foot = $1.29
Cost of 16.5 cubic feet = [tex]1.29 \times 16.5[/tex]
Cost of 4.5 cubic foot = [tex]1.29 \times 45[/tex]
So, Total cost : [tex]1.29 \times 45+1.29 \times 16.5[/tex]
[tex]1.29 (45+16.5)[/tex]
So, expression shows the total cost in dollars of the mulch is :
[tex]1.29 \times 45+1.29 \times 16.5[/tex] or [tex]1.29 (45+16.5)[/tex]
