Q: Lighters cost $1.75 each at the gas station, or $5.00 per pack of twelve on Amazon. How much would Amanda save by buying 24 lighters online instead of at the gas station?
A: First find how many packs Amanda would have to buy on Amazon: 24 lighters / 12 lighters / pack = 2 packs. Then multiply that number by the cost per pack to find the total cost from Amazon: 2 packs * $5 / pack = $10. Then multiply the total number of lighters Amanda buys by the cost per lighter at the gas station: 24 lighters * $1.75 / lighter = $42. Then subtract the total Amazon cost from the total gas station cost to find the savings: $42 - $10 = $32. The answer is 32.

Question: Helga went shopping for a new pair of shoes. At the first store, she tried on 7 pairs of shoes. At the second store, she tried on 2 more pairs than at the first store. At the third store, she did not try on any shoes, but she did buy a scarf. But at the fourth store, she tried on twice as many pairs of shoes as she did at all three other stores combined, before finally choosing a pair to buy. What is the total number of pairs of shoes Helga tried on before buying her new shoes?
Answer: At the second store, she tried on 7 + 2 = 9 pairs of shoes. Therefore, at the first three stores, she tried on 7 + 9 + 0 = 16 pairs of shoes. At the fourth store, she tried on 16 * 2 = 32 pairs of shoes. Thus, in total, she tried on 16 + 32 = 48 pairs of shoes. The answer is 48.
Q: Lydia is planning a road trip with her family and is trying to plan a route. She has 60 liters of fuel and she will use all of this during her trip. She isn't sure how much fuel she is going to use in the first third of the trip but she knows she will need a third of all of her fuel for the second third of the trip, and half this amount for the final third of the trip. How much fuel, in liters, can Lydia use in the first third of the trip?
A:
In the second third of the trip, Lydia is going to use 60 liters of fuel / 3 = 20 liters of fuel. In the final third of the trip, she needs half of this amount so she is going to be using 20 liters / 2 = 10 liters of fuel. So in the first third, Lydia used the remaining amount of fuel which is 60 total liters of fuel – 20 liters of fuel in the second third – 10 liters of fuel in the final third = 30 liters of fuel. The answer is 30.

In the second third of the trip, Lydia is going to use 60 liters of fuel / 3 = 20 liters of fuel. In the final third of the trip, she needs half of this amount so she is going to be using 20 liters / 2 = 10 liters of fuel. So in the first third, Lydia used the remaining amount of fuel which is 60 total liters of fuel – 20 liters of fuel in the second third – 10 liters of fuel in the final third = 30 liters of fuel.
