Question

Ahman has a lawn care business. he charges $25 per lawn to mow the grass. if his monthly expenses are $100, how many lawns must he mow in order to make a profit of at least $250 per month?

Answer 1

14

Explanation:

you can write an equation to represent the situation:

let x represent the number of lawns he has to mow

then, the monthly profit would be 25x - 100.

in order to make $250, this equation has to be equal to 250:

`25x-100=250`

now, solve this:

add 100 to both sides

`25x = 350`

divide both sides by 25

`x = 14`

he must mow 14 lawns
