[Question]Tony made a sandwich with two slices of bread for lunch every day this week. On Saturday, he was extra hungry from doing yard work and made two sandwiches. How many slices of bread are left from the 22-slice loaf Tony started with?
[Answer]There are 7 days in a week, so Tony made 1 * 7 = 7 sandwiches. On Saturday, he made 1 extra sandwich, so he made 7 + 1 = 8 sandwiches this week. A sandwich has 2 slices of bread, so he used 8 * 2 = 16 slices. Thus, Tony has 22 - 16 = 6 slices of bread left. The answer is 6.

[Question]Jill is painting her 20 toenails and fingernails. She paints 6 of her nails purple, 8 of them blue, and the rest striped. What is the difference in percentage points between the percentage of nails painted blue and the percentage painted striped?
[Answer]First find the total number of striped nails: 20 nails - 6 nails - 8 nails = 6 nails. Then divide the number of blue nails by the number of total nails and multiply by 100% to express the answer as a percentage: 8 blue nails / 20 total nails * 100% = 40%. Then divide the number of striped nails by the number of total nails and multiply by 100% to express the answer as a percentage: 6 striped nails / 20 total nails * 100% = 30%. Then subtract the percentage of striped nails from the percentage of blue nails to find the difference: 40% - 30% = 10%. The answer is 10.

[Question]A mathematician is working on two projects. He has one week to write 518 maths questions for one project and 476 questions for another project. If he completes the same number of questions every day, how many should he aim to complete each day?

[Question]John adopts a dog from a shelter. The dog ends up having health problems and this requires 3 vet appointments, which cost $400 each. After the first appointment, John paid $100 for pet insurance that covers 80% of the subsequent visits. How much did he pay in total?
[Answer]
He got a discount of 400 * .8 = $320. He got that discount for 3 - 1 = 2 visits. So each of those visits cost 400 - 320 = $80. So he paid 2 * 80 = $160 for those visits. That means he paid a total of 400 + 160 + 100 = $660. The answer is 660.
