Hi there! I can help! So we already know that $99 is the cost of the bread making machine. Buying the first loaf of bread would be $2.19 and the total cost of machine and loaf is $99.45. For two loafs of bread is $4.38 store bough and $99.90 hand made. Three slices of bread bought from the store would be $6.57 and $100.35 hand made. If you keep doing the same pattern, the answer will eventually come up, but even after 50 loaves of store bought bread, the total would still be $109.50 and $121.50 for bread and hand made total costs. On 57th slice of bread, buying from the store would total $124.83 and having it hand made would be $124.65. You would have to make 57 whole loaves of bread in order for the cost of the machine and ingredients to be less than the cost of buying the same size loaves from the store.
