[Question]: Jeff committed to run for an hour a day during weekdays. On Thursday, he cut short his run by 20 minutes but was able to jog 10 minutes more on Friday. How many minutes was he able to run for that week?
[Answer]: Jeff was able to run a total of 60 x 3 = 180 minutes from Monday to Wednesday. On Thursday, Jeff ran for 60 - 20 = 40 minutes only. On Friday, he ran for 60 + 10 = 70 minutes. Therefore, Jeff ran a total of 180 + 40 + 70 = 290 minutes.
So the answer is 290.

[Question]: Three plastic chairs cost as much as a portable table. Five plastic chairs cost $55. If Manny wants to buy one portable table and two chairs, how much will be left in his $100?
[Answer]:
Each plastic chair costs $55 / 5 = $11. Two chairs cost $11 x 2 = $22. A portable table costs $11 x 3 = $33. Manny has to pay a total of $22 + $33 = $55. Thus, Manny will be left with $100 - $55 = $45.
So the answer is 45.
