math problem #1

1. You've gone to the movies with your friends and offered to buy your four friends and yourself popcorn and a drink. The total with tax for each drink is $2.73 and the total for each bag of popcorn is $3.19.

Estimate how much money you need to have in order to buy all of the popcorn and drinks.

Solution: first, estimate how much money you need for 1 popcorn and 1 drink. 3.19 + 2.73 = 5.92 >estimate 3 + 3 = 6

then multiply the result you have, which is 6, with 5 (4 friends and you) . 5.92 X 5 = 29.60 >estimate 6 X 5 = 30

Answer: You need $30.00 to pay for all the drinks & popcorn. It's been rounded from $29.60

Anyone have a different set of numbers that you rounded the popcorn and drink off to?

If we were to only buy popcorn you would estimate the total at $3.00 x 6 = $18.00 yet wouldn't you need more money?
