Q: Kathryn moved to a new city for the new job she had landed two weeks ago. Her rent was $1200, 1/2 of what she spent on food and travel expenses in a month. Luckily, she found a new friend Shelby, who moved in with her to share the rent. If her salary was $5000 per month, how much money remained after her expenses?
A: If the rent is half what she spends on food and travel expenses, she spends 1200 * 2 = $2400 on food and travel costs. When her friend moved in and shared the rent costs with her, she started paying 1 / 2 * 1200 = $600 in rent costs. Her total monthly expenses is now 600 + 2400 = $3000. When she deducts her monthly expenses from her salary, she has $5000 - $3000 = $2000 remaining. The answer is 2000.

Q: A garden store sells packages of pumpkin seeds for $2.50, tomato seeds for $1.50, and chili pepper seeds for $0.90. Harry is planning to plant three different types of vegetables on his farm. How much will Harry have to spend if he wants to buy three packets of pumpkin seeds, four packets of tomato seeds, and five packets of chili pepper seeds?
A: The cost of three packets of pumpkin seeds is 3 x $2.50 = $7.50. The cost of four packets of tomato seeds is 4 x $1.50 = $6. And, the cost of five packets of chili pepper seeds is 5 x $0.90 = $4.50.                                 Therefore, Harry will spend $7.50 + $6 + $4.50 = $18. The answer is 18.
