[Question]Due to the restrictions of Coronavirus, Mr. Trent, the local store owner, increased the prices of goods at his store by 15% each to make the same income he was making before. If buying an orange was $40 and the price of purchasing a mango was $50, calculate how much it costs in total now to buy ten oranges and ten mangoes at the new prices.
[Answer]If the initial price of orange was $40, after the increase, the price rose by 15 / 100 * $40 = $6. The total price of buying an orange at the new price is $6 + $40 = $46. For the mango, the price increased by 15 / 100 * $50 = 7.5. The price of purchasing a mango at the new price is $50 + $7.5 = 57.5. To buy ten oranges it would cost $46 * 10 = $460. To buy 10 mangoes, it now costs $57.5 * 10 = $575. The total cost of buying ten oranges and ten mangoes is $575 + $460 = $1035. The answer is 1035.

[Question]James is sitting outside, counting how many people go past him in vehicles. He has counted 52 vehicles so far today. He saw 12 trucks, a couple of buses, twice as many taxis, some motorbikes, and 30 cars. If the trucks held 2 people each, the buses held 15 people each, the taxis held 2 people each, the motorbikes held 1 person each, and the cars held 3 people each, how many passengers has James seen today?
[Answer]In the trucks, James saw 12 * 2 = 24 people. In the buses, he saw 2 * 15 = 30 people. He saw 2 * 2 = 4 taxis go past him. Therefore, he saw 4 * 2 = 8 people in the taxis. In the cars, he saw 30 * 3 = 90 people. Since we know how many vehicles James saw in total, we know that he saw 52 – 12 – 2 – 4 – 30 = 4 motorbikes. So, he saw 4 * 1 = 4 people on motorbikes. He has therefore seen a total of 24 + 30 + 8 + 90 + 4 = 156 people. The answer is 156.

[Question]A boy squirrel gathers 6 walnuts and carries them to his burrow in the tree, adding to the 12 already there, and dropping 1 on the way. The girl squirrel brings 5 more walnuts to their burrow and eats 2. How many walnuts are left?
[Answer]With the boy’s contribution, there are 12 + 6 = 18 walnuts. When he drops 1, now they have 18 - 1 = 17 walnuts. The girl adds to their stash, making the count 17 + 5 = 22 walnuts. When the girl eats 2, the final count is 22 - 2 = 20 walnuts. The answer is 20.

[Question]Frank's laundry detergent is double concentrated and will wash 80 loads of laundry. His detergent is usually $25.00 a bottle but they're having a sale. If he buys 2 bottles, both bottles will drop to $20.00 a bottle. How much does he spend, in cents, per load of laundry, if he buys 2 bottles of detergent?
[Answer]
If he buys 2 bottles, the price drops to $20.00 per bottle so they cost 2 * 20 = $40.00. He can get 80 loads of laundry per bottle and he bought 2 bottles so that's 80 * 2 = 160 loads of laundry. The detergent cost $40.00 and he will be able to wash 160 loads of laundry so each load costs 40 / 160 = $0.25. The answer is 25.
