Question

Oscar paid $7.75 for a movie ticket. He wants to buy popcorn for $3.75 and a drink for $2.88. Oscar had $20 to spend at the theatre. Which statement best describes if an exact total or an approximate total should be calculated? A. The cashier can round the prices to the nearest dollar to make it faster to give Oscar his change. B. Oscar must add the 3 amounts exactly so he will know if he has enough money to buy the drink. C. Oscar can round the prices to the nearest dollar and then add to estimate if he has enough money.

Answer 1

C. or B., but B is probably the answer you want.

Why?

Considering the fact that the prices are very close to the next dollar, C would work, but B would be more accurate, and both methods would tell him if he had enough money, so both would technically work.

Answer 2

B. Oscar must add the 3 amounts exactly so he will know if he has enough money to buy the drink.
