You want to buy a TV that regularly costs $250. You can either buy the TV from a nearby store or from a store that's downtown. Relative to going to the nearby store, driving downtown involves additional time and gas. The downtown store, however, has a 10% off sale this week. Last week you drove downtown to save $20 on some concert tickets, a 15% savings. Should you drive downtown to buy the TV?

Question

Quizplus · Accepted Answer

Driving downtown to buy the TV will involve additional costs for gas and time, but the 10% discount at the downtown store will save $25. Therefore, the total cost of buying the TV downtown would be $225. This is a savings of $25, which is more than the $20 saved on concert tickets last week. Therefore, it makes sense to drive downtown to buy the TV and take advantage of the sale.
