5. Martin-Gay, Beginning Algebra, 5ed 55 I Introduction: II Body: A car rental agency advertised renting a Buick Century for $24.95 per day and $0.29 per mile. If you rent this car for 2 days, how many whole miles can you drive on a $100 budget? Let x = the number of whole miles driven 0.29x = the cost for mileage driven Daily costs 2(24.95) mileage costs 0.29x plus + is equal to = 100 maximum budget

6. Martin-Gay, Beginning Algebra, 5ed 66 II Body Continued: 2(24.95) + 0.29x = 100 49.90 + 0.29x = 100 Simplify left side. 0.29x = 50.10 Simplify both sides. Divide both sides by 0.29. x  172.75 Simplify both sides. Subtract 49.90 from both sides.49.90 – 49.90 + 0.29x = 100 – 49.90 The maximum number of whole number miles is 172. III Conclusion:
