[Question]Alex is saving up for a new car. He already has $14,500 saved up and the car costs $14,600. He decides that to make the last of the money he will deliver groceries for people in the neighborhood. He charges $1.5 per trip and then 5% of the price of the groceries. If he makes 40 trips and has saved up enough, how many dollars' worth of groceries did he deliver?
[Answer]He needs to save up $100 because 14,600 - 14,500 = 100. He earned $60 off trips because 40 x 1.5 = 60. He earned $40 off groceries because 100 - 60 = 40. He delivered $800 in groceries because 40 / .05 = 800. The answer is 800.

[Question]Mary is trying to count the animals in the petting zoo, but they kept moving around so she double-counts 7 sheep and forgets to count 3 pigs. If Mary thinks there are 60 animals, how many are there really?
[Answer]First subtract the 7 double - counted animals from Mary's total: 60 animals - 7 animals = 53 animals. Then add the animals she missed to find the real total: 53 animals + 3 pigs = 56 animals. The answer is 56.

[Question]Reuben opens a sandwich shop selling his namesake sandwich and pastrami sandwiches. Pastrami cost $2 more than the Reuben. He sells 10 Reubens and 5 Pastrami sandwiches and earns $55. How much does a pastrami sandwich cost?
[Answer]If X = "Price of Reuben" We know that 10(X) + 5(X + 2) = 55. Therefore 10X + 5X + 10 = 55. Therefore 15X = 45. Therefore, the price of a Reuben is $3 because 45 / 15 = 3. The price of pastrami is $5 because 3 + 2 = 5. The answer is 5.

[Question]Oula and Tona work for a delivery service company, supplying different parts of their state with milk products. They are paid $100 for each delivery made in a day. In a particular month, Oula made 96 deliveries while Tona made 3/4 times as many deliveries as Oula. Calculate their difference in pay that month.
[Answer]
Oula's earnings for that month are 96 * $100 = $9600. Tona made 3 / 4 * 96 = 72 deliveries that month. Tona's total earnings for that month are 72 * $100 = $7200. Their difference in pay is $9600 - $7200 = $2400. The answer is 2400.
