Question

It requires 15 gallons of mulch to cover 5 flowerbeds.How many gallons are needed to cover 7 flowerbeds?

Answer 1

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

Answer 2

You need to work out how much you need for 1 flowerbed,
So, 15÷5= 3. 3 gallons =1 flowerbed
Then, 3 X 7 = 21 Gallons.
