Q: Jenny wants to heat a dish for dinner. It needs to be at 100 degrees before it is ready to eat. It is 20 degrees when she places it in the oven, and it heats up 5 degrees every minute. How many minutes will it take to be ready?
A: To determine this, we must first figure out the required change in temperature. To do this, we perform 100 - 20 = 80 degrees of required temperature change. Next, we divide this amount by the rate of change per minute, performing 80 / 5 = 16 minutes of cooking time. The answer is 16.

[Question]Tom was putting hardwood flooring into his living room that measured 16' long and 20' wide. The flooring comes 10 sq ft per box and he has already put down 250 sq ft of flooring. How many more boxes does Tom need to complete the job?
[Answer]The entire sq ft of the living room is LxW so the room is 16x20 = 320 sq ft. Tom has already put down 250 sq ft so he needs to put down 320 - 250 = 70 sq ft of flooring. The boxes contain 10 sq ft of flooring per box and he needs 70 more sq ft of flooring so he needs 70 / 10 = 7 more boxes. The answer is 7.
Q: Oliver had $9, then he saved $5 from his allowance and spent $4 on a frisbee and $3 on a puzzle. His friend gives him another $8 as it's his birthday. How much money does Oliver have left?
A: The total amount of money saved is $9 + $5 = $14. The total cost of the frisbee and the puzzle is $4 + $3 = $7. So Oliver has $14 - $7 = $7 left. His friend gives him $8, so now he has $7 + $8 = $15. The answer is 15.
Question: Frank is practicing a new dance move. It starts with him take 5 steps back, and then 10 steps forward, and then 2 steps back, and then double that amount forward. How many steps forward is Frank from his original starting point?
Answer: Frank stars by taking 10 steps forward from a position 5 steps behind where he started, so he's 10 - 5 = 5 steps forward in total. Frank then takes 2 steps back, meaning he's now 5 - 2 = 3 steps forward in total from where he began. He then takes double the previous amount of 2 steps forward, so he takes 2 * 2 = 4 steps forward. Since Frank was 3 steps forward before that, that means Frank finishes 3 + 4 = 7 steps forward. The answer is 7.
Q: Preston has a sandwich shop. He charges $5 for each sandwich. He also charges $20 for a delivery fee. Abra Company orders 18 sandwiches from Preston and also tips him 10%. How much total, in dollars, did Preston receive?
A:
First, find the price of the sandwiches $5 per sandwich * 18 sandwiches = $90. Now add in the delivery fee $90 + $20 = $110. Now the tip $110 * 0.10 = $11. Add the tip to the price of the sandwiches $110 + $11 = $121 in total. The answer is 121.
