Q: Anna has a certain number of phone chargers and five times more laptop chargers than phone chargers. If she has 24 chargers total, how many phone chargers does she have?
A: Let p be the number of phone chargers Anna has and l be the number of laptop chargers. We know that l = 5p and l + p = 24. Substituting the first equation into the second equation, we get 5p + p = 24. Combining like terms, we get 6p = 24. Dividing both sides of the equation by 6, we get p = 4. The answer is 4.
Question: Trey has 7 times as many turtles as Kris. Kris has 1/4 as many turtles as Kristen has. How many more turtles does Trey have than Kristen, if Kristen has 12?

[Question]Karen is constantly trying to stop the raccoons from getting in her trash. The first lock she tries stalls them for 5 minutes. The next lock stalls them for 3 minutes less than three times as long as the first lock. When Karen tries both locks at once, it stalled the raccoons for five times as long as the second lock alone. How long is that?
[Answer]First find how long the second lock stalls them: 5 minutes * 3 - 3 minutes = 12 minutes. Then multiply that amount by 5 to find the total time the third lock stall the raccoon: 12 minutes * 5 = 60 minutes. The answer is 60.
Q: Jorge has an equal number of baseball cards as Matias, who has 6 fewer cards than Carlos. If Carlos has 20 baseball cards, what is the total number of baseball cards the three have?
A: If Carlos has 20 cards, Matias has 20 - 6 = 14 baseball cards. Since Matias and Jorge have the same amount of baseball cards, the total number of cards the three have is 14 + 14 + 20 = 48 cards. The answer is 48.
Question: John adopts a dog from a shelter. The dog ends up having health problems and this requires 3 vet appointments, which cost $400 each. After the first appointment, John paid $100 for pet insurance that covers 80% of the subsequent visits. How much did he pay in total?
Answer: He got a discount of 400 * .8 = $320. He got that discount for 3 - 1 = 2 visits. So each of those visits cost 400 - 320 = $80. So he paid 2 * 80 = $160 for those visits. That means he paid a total of 400 + 160 + 100 = $660. The answer is 660.
