Answer provided by our tutors
Let
x = cubic feet of soil
y = cubic feet of mulch
x : y = 2 : 3
3x = 2y
The volume of a rectangular garden bed is 60 cubic feet:
x + y = 60
We have the following system of equations:
3x = 2y
x + y = 60
........
........
x = 24 ft^3
y = 36 ft^3
You need 24 ft^3 of soil and 36 ft^3 of mulch.
