We have a question: Leo and Agrey went fishing. Agrey caught 20 more fish than Leo. If Leo caught 40 fish, what's the total number of fish they caught together?
And an answer: 100
So how you got the answer?
Agrey caught 40 + 20 = 60 fish. The total number of fish they caught is 60 + 40 = 100 fish.

We have a question: Abraham is buying some toiletries and creates a budget of $60 for his shopping. He buys 4 shower gels for $4 each, a tube of toothpaste for $3, and a box of laundry detergent. If he has $30 remaining in his budget, how much money, in dollars, did Abraham spend on the box of laundry detergent?
And an answer: 11
So how you got the answer?
Shower gel costs Abraham 4 shower gels * $4 = $16. So the shower gel and toothpaste combined have cost him $16 + $3 = $19. He had money remaining in his budget so the total cost of his shopping must have been $60 – $30 = $30. The box of laundry detergent therefore cost him $30 – $19 = $11.

We have a question: Jack is running a bake sale to help pay for his basketball team's uniforms. He's already sold 4 brownies for $3 each and 5 lemon squares for $2 each. If Jack's goal is to make $50 and he sells cookies for $4 each, how many cookies does he need to sell to reach his goal?
And an answer: 7
So how you got the answer?
Jack earned from the brownies $3 per brownie * 4 brownies = $12. Jack earned from the lemon squares $2 per square * 5 squares = $10. He still needs to earn $50 - $12 - $10 = $28. He sells cookies for $4 each, so Jack still needs to sell $28 / $4 = 7 cookies.
