The cost of a car rental is $35 per day plus 21 cents per mile. You are on a daily budget of $98. Write and solve an inequality to find the greatest distance you can drive each day while staying within your budget.
Let x = mileage 98 >= 35 + .21x Solving for x: 98 >= 35 + .21x 63 >= .21x 300 >= x . This says that if the total mileage is 300 miles or less he will be within his budget.
