Question

Harvey plans to use 5 ft of shelving for four shelves whose lengths are to be a series of consecutive even numbers. How many inches long should each shelf be?

Answer 1

1 ft = 12 inc, so
5 ft = 60 inc
let that numbers are : x, x+2, x+4,x+6
x+x+2+x+4+x+6 = 60
4x+12=60
4x=60-12
4x=48
x=12
thus, each shelf be : 12,14,16,18 (in inc)
