[Question]The news announced a $0.4 oil price rollback this Friday. Mr. Deane decided to only fill his gas tank with 10 liters of gas today and then another 25 liters on Friday. If the cost per liter of gas is $1.4 today, how much will Mr. Deane spend for his 35 liters of gas?
[Answer]Mr. Deane will spend $1.4 / liter x 10 liters = $14 for the 10 liters of gas today. The price of the gas per liter on Friday will be $1.4 / liter - $0.4 / liter = $1 / liter. So, he will spend $1 / liter x 25 liters = $25 for the 25 liters of gas on Friday. Thus, Mr. Deane will spend a total of $14 + $25 = $39 for the 35 liters of gas. The answer is 39.
Q: A supermarket receives a delivery of 15 cases of tins of beans. Each case contains 24 tins. If 5% of the tins are damaged and thrown away, how many tins of beans are left?
A: The supermarket has 15 cases × 24 tins / case = 360 tins of beans delivered to them. There are 360 tins × 0.05 = 18 tins that are damaged and unsellable. So in the end, there are 360 tins - 18 tins = 342 tins of beans that are left. The answer is 342.
Question: A local restaurant was offering a "Build Your Own Hot Brownie" dessert. The brownie cost $2.50 and each scoop of ice cream costs $1.00. Any syrup costs $0.50 and nuts cost $1.50. If Juanita orders the brownie with 2 scoops of ice cream, double syrup, and nuts, how much will her dessert cost?
Answer: She orders 2 scoops of ice cream that's $1.00 per scoop so the ice cream costs 2 * 1 = $2.00. She wants double syrup. The syrup is $0.50 so that will cost 2 * .50 = $1.00. The brownie is $2.50, the ice cream will be $2.00, the syrup will be $1.00 and the nuts will be $1.50 bringing her total to 2.5 + 2 + 1 + 1.5 = $7.00. The answer is 7.
[Question]There were 80 cars in a parking lot. At lunchtime, 13 cars left the parking lot but 5 more cars went in than left. How many cars are in the parking lot now?
[Answer]There are 80 - 13 = 67 cars in the parking lot after 13 went out. 13 + 5 = 18 cars went in the parking lot at lunchtime. So, there are 67 + 18 = 85 cars in the parking lot now. The answer is 85.
Q: If Jenna has twice as much money in her bank account as Phil does, and Phil has one-third the amount of money that Bob has in his account, and Bob has $60 in his account, how much less money does Jenna have in her account than Bob?
A: If Phil has one - third of the amount that Bob does, that means he has $60 / 3 = $20 in his account. Since Jenna has twice as much money as Phil, that means she has $20 * 2 = 40 in her account. Since Bob has $60 in his account, that means he has $60 - $40 = $20 more than Jenna. The answer is 20.

Half of the 400 vehicles for sale on the lot are Dodges, or a total of 400 / 2 = 200 Dodge vehicles. Since there are half as many Hyundai vehicles on the lot as there are Dodge vehicles, then there are 200 / 2 = 100 Hyundai vehicles on the lot. Since the remainder of the vehicles are Kias, then there are 400 - 200 - 100 = 100 Kia vehicles for sale on the lot. The answer is 100.
