Question: Five friends eat at Wendy's and ordered the following: a platter of Taco Salad that cost $10, 5 orders of Dave's Single hamburger that cost $5 each, 4 sets of french fries that cost $2.50, and 5 cups of peach lemonade that cost $2 each. How much will each of them pay if they will split the bill equally?
Answer: Step-by-step reasoning process: The cost of 5 pieces of Dave's Single hamburger is $5 x 5 = $25. The cost of 4 sets of french fries is $2.50 x 4 = $10. The cost of 5 cups of peach lemonade is $2 x 5 = $10. So, their total bill is $10 + $25 + $10 + $10 = $55. Therefore, each of them will contribute $55 / 5 = $11.
So the answer is 11.

Question: Tim decides to get animals for his zoo. He buys 3 goats for $400 each. He gets twice as many llamas which cost 50% more each. How much did he spend?
Answer: Step-by-step reasoning process: The goats cost 3 * 400 = $1200. He buys 3 * 2 = 6 llamas. Each llama cost 400 * 1.5 = $600. So he spends 600 * 6 = $3600 on llamas. So the total cost was 1200 + 3600 = $4800.
So the answer is 4800.

Question: There were 50 racers in a bicycle charity race at the beginning of the race. After 20 minutes, 30 more racers joined the race. The total number of racers doubled after another 30 minutes. If at the end of the race only 130 people finished the race, what's the total number of people who dropped before finishing the race?
Answer: Step-by-step reasoning process: At the start, there were 50 racers, who were joined by 30 more racers, thus 50 + 30 = 80 racers. After 30 more minutes, the number of racers doubled, totaling 80 * 2 = 160 racers. If the number of racers who finished is 130, the 160 - 130 = 30 racers dropped before finishing.
So the answer is 30.

Question: James buys 5 packs of beef that are 4 pounds each. The price of beef is $5.50 per pound. How much did he pay?

So the answer is 110.
