Q: Josh’s mom gives him $20 to go shopping at the mall. He buys a hat for $10 and a pencil for $2. Then he buys four cookies. If each cookie costs $1.25, how much money does Josh have left?
A: After buying a hat, Josh has $20 - $10 = $10. After buying a pencil, Josh has $10 - $2 = $8. The total cost of cookies is 4 * $1.25 = $5. After buying the cookies, Josh has $8 - $5 = $3. The answer is 3.

Q: Elisa and her two friends went out to dinner. Each of them ordered a meal worth $10. Afterwards, they each had a scoop of the same kind of ice cream. If the $45 Elisa had was enough to pay for everything, what was the cost of a scoop of ice cream?
A: The three friends had meals worth 10 * 3 = 30 dollars. If they paid for the meals only, they would have remained with 45 - 30 = 15 dollars. Dividing the remaining amount by the number of ice cream scoops gives 15 / 3 = 5 dollars. Each scoop of ice cream cost 5 dollars. The answer is 5.
