Marco runs a mobile pet grooming business. He pays $50 per month for insurance on his van
plus $2.50 per gallon of gasoline. Write an inequality to find the number of gallons of gasoline
purchased if he wants these costs to be no more than $200 per month, where g is the number of
gallons. Then solve.
