A: He catches 8 * 12 = 96 crabs a day. So he makes 96 * 5 = $480 per day. That means he makes 7 * 480 = $3360 a day. The answer is 3360.
Question: After 100 new people move into a town, 400 of the original population move out. Every year afterward, the town’s population is halved. After 4 years, the population is 60 people. Before the new people moved in, how many people lived in the town?
Answer: If the population is halving then at the end of the third year, the population must have been 60 people in the fourth year * 2 = 120 people. In the second year, the population was 120 people in the third year * 2 = 240 people. And in the first year, the population was 240 people in the third year * 2 = 480 people. Additional people moved out in the first year, so accounting for these shows the population was 480 people + 400 people who moved out = 880 people. Then removing the new people shows there were originally 880 people – 100 new people = 780 people. The answer is 780.
[Question]Sofia and her mother go to the grocery store and buys 10kgs of oranges to be used in their home for the week. While at the store, Sofia's father calls and says they're to add 5 more kgs since their neighbor also wanted some supplies. When they reach home, they estimated that for the next coming two weeks they'll have to buy twice as many oranges each week for the supplies to be enough. What the total quantity of oranges they would have bought after the three weeks.
[Answer]For the first week, they bought 10 + 5 = 15kgs. For the next week, they bought twice the quantity of oranges which is 2 * 15 = 30kgs. For the next two weeks, the total quantity of oranges bought is 30 * 2 = 60 kgs. The total quantity for the three weeks is 60 + 15 = 75 kgs. The answer is 75.
Q: Ron ate pizza with his friends the other day. If they ordered a 12-slice pizza and each of them ate 4 slices, how many friends were there with Ron?
A: Let the number of friends that ate with Ron be represented by F. That means the total amount of people that ate that day were 1 + F. If each of them ate 4 slices, and the pizza only has 12 slices, that means there could only have been 12 / 4 = 3 people eating. If the total number of people eating was 3, and if was also represented by 1 + F then we have 3 = 1 + F. Solving for F we have 3 - 1 = F. F = 2 friends ate with Ron. The answer is 2.
Question: Mary, Jess, and Christina want to decorate a party room with balloons. Each person inflates balloons at different speeds, and they only have 30 minutes to inflate as many balloons as possible. Mary inflates 10 balloons per minute, Jess inflates 7 balloons per minute and Christina came 15 minutes late and was the slowest one inflating 4 balloons per minute. How many balloons can they inflate before running out of time?
Answer: Mary will inflate a total of 10 balloons / minute x 30 minutes = 300 balloons. Jess will inflate a total of 7 balloons / minute x 30 minutes = 210 balloons. Christina will inflate a total of 4 balloons / minute x 15 minutes = 60 balloons. Combining all balloons, they made 300 balloons + 210 balloons + 60 balloons = 570 balloons. The answer is 570.
