[Question]: Every day Janet spends 8 minutes looking for her keys and another 3 minutes complaining after she finds them. If Janet stops losing her keys, how many minutes will she save every week?
[Answer]: First find the total time Janet spends looking for her key and complaining each day: 8 minutes / day + 3 minutes / day = 11 minutes / day. Then multiply that number by the number of days in a week to find the weekly time spent: 11 minutes / day * 7 days / week = 77 minutes.
So the answer is 77.

[Question]: Two pieces of bread are needed for one regular sandwich. 3 pieces of bread are needed for a double meat sandwich. How many pieces of bread are needed for 14 regular sandwiches and 12 double meat sandwiches?
[Answer]: Regular = 2 * 14 = 28 pieces. Double = 3 * 12 = 36 pieces. 28 + 36 = 64 pieces. 64 pieces of bread are needed for those sandwiches.
So the answer is 64.

[Question]: Jeff is collecting matchbox cars. He has twice as many cars as trucks. He has 60 total vehicles. How many trucks does he have?
[Answer]:
The number of trucks + 2(number of trucks) = 60. Therefore 3(number of trucks) = 60. Number of trucks = 20 because 60 / 3 = 20.
So the answer is 20.
