Q: Anna has 3 times as many toys as Mandy and 2 fewer toys than Amanda. If they have 142 toys all together, how many toys does Mandy have?
A: Let x be the number of toys Mandy has. Anna has 3 * x toys. Amanda has 3 * x + 2 toys. x + 3 * x + 3 * x + 2 = 142. 7 * x + 2 = 142. 7 * x = 140. x = 20. The answer is 20.
Question: Dilan, Martha, Phillip, and Veronica went to the park together to have some fun. They all had a different number of marbles: Dilan had 14 marbles, Martha had 20 marbles, Phillip had 19 marbles and finally, Veronica had only 7 marbles. They wanted to redistribute the marbles so they each had an equal number. How many marbles did each friend have at the end of the day?
Answer: First find the total numbers of marbles: 14 + 20 + 19 + 7 = 60 marbles. After sharing them equally each person will get 60 marbles / 4 people = 15 marbles / person. The answer is 15.
[Question]Emma bought a loaf of bread that had a certain number of slices. Her little cousin Andy ate 3 slices from the bread at two different points in time, and then Emma decided she would make toast with the remaining slices. If she uses 2 slices of bread to make 1 piece of toast bread, how many slices were in the original loaf if she was able to make 10 pieces of toast bread and had 1 slice of bread left?
[Answer]Little Andy ate 3 slices 2 times giving a total of 3 * 2 = 6 slices of bread. 1 piece of toast bread requires 2 slices of bread so 10 pieces need 10 * 2 = 20 slices of bread. There is 1 slice of bread left so in total there were 6 + 20 + 1 = 27 slices of bread in the loaf. The answer is 27.
Q: Allie's making guacamole for a party. Each batch requires 4 avocados and serves about 6 people. If 42 people are going to be at the party including her, how many avocados does she need?
A: Each batch serves 6 people, and there are 42 people coming to the party, so she needs to make 42 / 6 = 7 batches. Each batch requires 4 avocados, so she will need 4 * 7 = 28 avocados. The answer is 28.
Question: Lori owns a carsharing company. There are three red cars and two white cars available to rent. Renting the white car costs $2 for every minute and the red car $3 for every minute. All cars were rented for 3 hours. How much money did Lori earn?
Answer: Both white cars were rented for 2 * 2 = $4 for every minute. All three red cars were rented for 3 * 3 = $9 for every minute. So all Lori's cars were rented for 4 + 9 = $13 for every minute. Three hours are 180 minutes, so Lori earned 13 * 180 = $2340 for renting all the cars. The answer is 2340.
Q: Barbeck has two times as many guitars as Steve, but Davey has three times as many guitars as Barbeck. If there are 27 guitars altogether, how many guitars does Davey have?
A:
Let x = the number of guitars Steve has. Barbeck has 2x guitars, and Davey has 3 * 2x = 6x guitars. 2x + 6x + x = 27. 9x = 27. x = 27 / 9 = 3 so Steve has 3 guitars. Barbeck has 2 * 3 = 6 guitars. And Davey has 3 * 6 = 18 guitars. The answer is 18.
