Answer:
35 gallons of mulch will cover 7 flowerbeds
Step-by-step explanation:
If it takes 15 gallons of mulch to cover 5 flowerbeds then we can represent the number of gallons per flowerbed.
The number of gallons per flowerbed = 15 gallons of mulch /5 flowerbeds
= 3 gallons of mulch/ flowerbeds
So it takes 3 gallons of mulch to cover 1 flowerbed.
Therefore for 7 flowerbeds we can determine the amount of gallons of mulch needed by using conversion factors:
= (3 gallons of mulch/ flower bed)×7 flowerbeds
= 21 gallons of mulch
Therefore 21 gallons of mulch will cover 7 flowerbeds
