Question

Moche started a summer business of mowing lawns. However, before he could mow lawns, he needed to purchase supplies (a lawnmower among other needs). Moche spent $395 gathering necessary materials. He makes on average $60 per lawn, mowed. Write an equation to show Moche his earnings for l lawns mowed.

Answer 1

gone money -$395

money per lawn $60

let x be lawn and f()= earnings


f(x)= 60x-396

Answer 2

`E= 60 l - 395`

Explanation:

Let E be the total earnings .

Cost of mowing 1 lawn = $60

Since he mowed l lawns

So, cost of mowing l lawns =
`60l`

So, he earned
`60l`

Now we are also given that he spent $395 gathering necessary materials.

So, the total earnings for l lawns mowed =
`60l-395`

So, required expression :
`E= 60 l - 395`

Hence an equation to show Moche his earnings for l lawns mowed is :

`E= 60 l - 395`
