[Question]: Sophie does 4 loads of laundry a week and uses 1 dryer sheet per load. A box of dryer sheets costs $5.50 and has 104 dryer sheets in a box. On her birthday, she was given wool dryer balls to use instead of dryer sheets. How much money does she save in a year not buying dryer sheets?
[Answer]: She does 4 loads of laundry a week and used 1 dryer sheet per load for a total of 4 * 1 = 4 dryer sheets in a week. She used 4 dryer sheets per week for 52 weeks for a total of 4 * 52 = 208 dryer sheets. Her box of dryer sheets has 104 sheets so she needs 208 / 104 = 2 boxes of dryer sheets. Each box costs $5.50 and she used 2 boxes so she now saves 5.50 * 2 = $11.00 by not buying dryer sheets.
So the answer is 11.

[Question]: Perry wants to buy a new modern bedroom set for $2000. He received $200.00 in gift cards over the holidays that he can use toward the set. The store is currently offering the entire set at 15% off. If he signs up for the store credit card and uses it to buy the set, he will save an additional 10% off on the discounted set. What is the final price of the set?
[Answer]: The bedroom set is $2000 and it’s currently 15% off so 2000 * .15 = $300.00 off. So the new price of the set is 2000 - 300 = $1,700.00. He signs up for the credit card so that’s 10% off so .10 * 1700 = $170.00. Now the set is 1700 - 170 = $1,530.00. He has a $200.00 gift card which brings the price to 1530 - 200 = $1,330.00.
So the answer is 1330.

[Question]: Mr. Shaefer harvested 500 lychees in a carton and took them to the market. He sold half of them and took home the remaining number of lychees where they ate 3/5 of them. Calculate the number of lychees remaining.
[Answer]:
At the market, Mr. Shaefer sold half of the lychees, which is 1 / 2 * 500 = 250. The remaining number of lychees is 500 - 250 = 250. At home, they ate 3 / 5 * 250 = 150 lychees. The total number of lychees remaining is 250 - 150 = 100.
So the answer is 100.
