Answer:
15
Step-by-step explanation:
We are given that
Total volume of soil needed=45 cubic feet
He has already soil=7.5 cubic feet
Volume of soil in each bag=2.5 cubic feet
We have to find the number of bags of soil required to purchase.
Remaining volume of soil=45-7.5=37.5 cubic feet
Number of bags of soil required=[tex]\frac{Remaining\;volume\;of\;soil}{volume\;of\;soil\;in\;each\;bag}[/tex]
Number of bags of soil required=[tex]\frac{37.5}{2.5}[/tex]
Number of bags of soil required=15
Hence, he should purchase 15 bags of soli.
