Jackson mows lawns to make money. It costs him $7 each week to advertise his business. It costs him $1.50 in gas to mow each lawn, and he charges $10.00 for each lawn he mows. Write an equation to model the amount of profit, P, he makes from mowing x lawns in one week.
Say he mows 1 lawn every day, per week. He'd spend a total of $10.50 on gas and $7 for an advertisement for that week. Which would equal his total profit being $52.50 per week is his business.
