Q: Mary bought 5 boxes of drinks at $6 each box and 10 boxes of pizzas at $14 each box for her pizza party. She paid $200 for all the items. How much change did she get back?
A: Mary spent 5 x $6 = $30 on drinks. She spent 10 x $14 = $140 on pizzas. She spent a total amount of $30 + $140 = $170. Therefore, Mary got a change of $200 - $170 = $30 after paying all the items for her pizza party. The answer is 30.
Question: Janet is trying to decide whether to quit her job and start freelancing. She works 40 hours a week at both jobs. She get paid $30/hour at her current job, and would get paid $40/hour as a freelancer. However, she'd have to pay an extra $25 a week in FICA taxes plus $400/month in healthcare premiums. How much more would Janet make per month as a freelancer if there are four weeks in a month?
Answer: First find the difference in hourly wages: $40 / hour - $30 / hour = $10 / hour. Then multiply that difference by the number of hours she works in a week to find the weekly difference: $10 / hour * 40 hours / week = $400 / week. Then multiply that amount by the number of weeks in a month to find the monthly difference in her earnings: $400 / week * 4 weeks / month = $1600 / month. Then find the total additional amount Janet pays in FICA taxes: $25 / week * 4 weeks / month = $100 / month. Then subtract Janet's extra FICA taxes and healthcare premium from the additional money she earns to find the net increase in her pay from freelancing: $1600 / month - $400 / month - $100 / month = $1100 / month. The answer is 1100.
[Question]A farmer harvested 250 potatoes. He bundled them in twenty-five's and sold each bundle for $1.90. He also harvested 320 carrots and bundled them in twenty's and sold each bundle for $2. If the farmer sold all his harvested crops, how much did he get in all?
[Answer]There are 250 / 25 = 10 bundles of potatoes. So, 20 bundles of potatoes amount to $1.9 x 10 = $19. There are 320 / 20 = 16 bundles of carrots. So, 16 bundles of carrots amount to $2 x 16 = $32. Hence, the farmer got $19 + $32 = $51 in all. The answer is 51.

Question: Daisy’s milk cow provides 16 cups of milk per day. 75% of the milk is consumed by Daisy’s kids. Daisy uses 50% of the remaining milk to cook with. How much milk is left over?
Answer: The cow provides 16 cups of milk per day and the kids consume 75% so they drink 16 * .75 = 12 cups of milk. The cow provides 16 cups of milk and the kids drink 12 cups leaving 16 - 12 = 4 cups of milk. Daisy uses 50% of the remaining 4 cups of milk to cook with so she uses .50 * 4 = 2 cups of milk. She had 4 cups of milk and used 2 cups to cook with so that leaves 4 - 2 = 2 cups of milk. The answer is 2.
