Question

Alan has a business mowing lawns for $20 per lawn and raking leaves for $0.75 per pile. His goal is to earn exactly $30 each time he mows a lawn and rakes leaves. If x represents the number of piles of leaves, which equation models Alan’s goal?

Answer 1

Explanation:

20+0.75x

20+0.75(14)

20+ 10.5 = 30.5

Answer 2

`0.75x+20=30`

Explanation:

Let x be the no. of piles of leaves

Cost of raking leaves per pile= $0.75

Cost of raking leaves x piles= 0.75 x

Cost of mowing lawn = $20

His goal is to earn exactly $30 each time he mows a lawn and rakes leaves.

So, equation becomes :
`0.75x+20=30`

Hence equation models Alan’s goal is
`0.75x+20=30`
