The cost of the breadmaker is $83. The cost of the bread-making supplies is $0.93 per week. The cost of buying a loaf of bread is $2.00 per week. The breadmaker will start saving Jarod money when the cost of the breadmaker plus the cost of the bread-making supplies is less than the cost of buying a loaf of bread.The cost of the breadmaker plus the cost of the bread-making supplies for 78 weeks is $83 + (0.93 * 78) = $150.94. The cost of buying a loaf of bread for 78 weeks is $2.00 * 78 = $156.00. Therefore, the breadmaker will start saving Jarod money after 78 weeks.
