Q: 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?
A: 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.

Q: There are 100 people in a theater. If 19 of these people have blue eyes, half of them have brown eyes, a quarter have black eyes, and the rest have green eyes, how many of them have green eyes?
A: 100 / 2 = 50 people in the theater have brown eyes. 100 / 4 = 25 people in the theater have black eyes. There are 50 + 25 + 19 = 94 people in the theater with either brown, black, or blue eyes. There are 100 - 94 = 6 people in the theater with green eyes. The answer is 6.

Q: Annie has some money. The restaurant next door sells hamburgers for $4 each. The restaurant across the street sells milkshakes for $5 each. Annie buys 8 hamburgers and 6 milkshakes. She has $70 left. How much money, in dollars, did Annie have at first?
A:
Annie spends 4 * 8 = 32 dollars on hamburgers. Annie spends 5 * 6 = 30 dollars on milkshakes. Annie spends 32 + 30 = 62 dollars on hamburgers and milkshakes. Annie had 62 + 70 = 132 dollars at first. The answer is 132.
