Amanda has to sell 80 tickets in 3 days so she can make enough money to go on vacation. On the first day, she sells 5 of her friends 4 tickets each. On the second day she sells 32 tickets. How many tickets does she need to sell on the third day to meet her goal?
Let's think: Amanda sells 4 tickets to 5 friends so she sells 4 * 5 = 20 tickets on her first day. On her second day, she sells 32 tickets for a total of 20 + 32 = 52 Tickets so far. Having 80 tickets as the goal, she needs to sell 80 - 52 = 28 Tickets on her last day.. The answer is: 28.

John can read a book 60% faster than his brother. If his brother takes 8 hours to read a book, how long would it take John to read 3 books?
Let's think: Reading 60% faster means John's brother takes 1 + .6 = 1.6 times as long as John to read. So John reads a book in 8 / 1.6 = 5 hours. So it would take John 5 * 3 = 15 hours to read 3 books.. The answer is: 15.

A single kabob stick has 4 cubes of beef. A slab of beef that costs $25 can be cut into 80 cubes. How much must Simon spend to make 40 kabob sticks?
Let's think: One slab of beef can make 80 / 4 = 20 kabob sticks. To make 40 kabob sticks, Simon needs 40 / 20 = 2 slabs of beef. Simon must spend $25 x 2 = $50.. The answer is: 50.

Lilith originally had five dozen water bottles that she needed to sell at $2 each to get exactly enough money to buy her friend a birthday gift. However, at the store, Lilith realized she could not sell at $2 because the regular price was $1.85 per water bottle in her town, and she had to reduce her price to $1.85 as well to sell her water bottles. Calculate the total amount of money Lilith will have to find to buy her friend the birthday gift after selling her water bottles at the reduced cost.
Let's think:
Lilith had 5 dozen water bottles, and since a dozen has 12 water bottles, the total number of water bottles she had was 12 bottles / dozen * 5 dozen = 60 bottles. To buy her friend the birthday gift, Lilith originally had to sell her water bottles for a total of 60 bottles * $2 / bottle = $120. When she reduced the price to $1.85 to meet the regular price, the total amount of money she had from the sales was $1.85 / bottle * 60 bottles = $111. To buy her friend the birthday gift, Lilith has to find $120 - $111 = $9 more.. The answer is: 9.
