Approximately how much will John need to pay if a pair of shoes cost $42.64, a pair of pants costs $37.99, and a shirt costs $21.34.
The key word, "approximately," indicates that we must round each of these values. Let's round to the nearest tens place because each of our answer choices is rounded to the tens place.
Shoes cost $42.64.
$42.64 rounded (down) to the nearest tens place is $40.
Pants cost $37.99.
$37.99 rounded (up) to the nearest tens place is $40.
A shirt costs $21.34.
$21.34 rounded (down) to the nearest tens place is $20.
Let's add up our estimated prices.
$40 + $40 + $20 =
$100.

Laura is going bowling with her friends this weekend and she is using some of the money that she has saved up from allowance and her birthday. She will have to pay a flat fee of $8 to rent her shoes and $10.50 per game she bowls. If she has planned to bowl 4 games and she is only taking $50 with her to the bowling alley will she have enough money? If yes, how much money will she have when she leaves the bowling alley?
The flat fee for the shoes will only be paid once since the shoes will be used for all four games. The cost per game will be paid each time one game finishes and a new one is started.
To calculate her cost add the fee for the shoes and the fee for each game played. That would be $8 (shoes) + $10.50 (game 1) + $10.50 (game 2) + $10.50 (game 3) + $10.50 (game 4) = $50 (total cost).
Laura had $50 with her so there was enough money and nothing left over when she left the bowling alley.
