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.

[Question]Laura wants to bake a cake for her mother. She checks the recipe and the pantry and sees that she needs to buy 2 cups of flour, 2 cups of sugar, a cup of butter, and two eggs. The flour costs $4. The sugar costs $2. The eggs cost $.5, and the butter costs $2.5. When she is done baking it, she cuts the cake into 6 slices. Her mother enjoys a piece the first two days. But on the third day, they discover that Kevin, her dog, ate the rest of the cake. How much did the amount the dog ate cost?
[Answer]The cake cost $9 in total because 4 + 2 + .5 + 2.5 = 9. Each slice costs $1.5 because 9 / 6 = 1.5. The dog ate 4 slices because 6 - 2 = 4. The amount the dog ate cost $6 because 4 x 1.5 = 6. The answer is 6.
Q: Zach baked cookies for a bake sale. On Monday he baked 32 cookies. On Tuesday he ran out of sugar and could only bake half of the number of cookies he baked the day before. On Wednesday he baked three times the number of cookies he did on Tuesday, but his brother ate 4 of those cookies. How many cookies did he have at the end of the three days?
A: On Tuesday he made 32 / 2 = 16 cookies. On Wednesday he made 16 * 3 = 48 cookies. Before his brother ate some he had 32 + 16 + 48 = 96 cookies. After his brother ate some he had 96 - 4 = 92 cookies. The answer is 92.
Question: Nicki spent the last year running a lot. For the first half of the year, she ran a total of 20 miles per week. For the second half of the year, she increased the mileage to 30 miles per week. How many miles total did she run for the year?
Answer:
Each half of the year consists of 52 / 2 = 26 weeks. For the first half of the year, Nicki ran a total of 20 * 26 = 520 miles. For the second half of the year, Nicki ran a total of 30 * 26 = 780 miles. For the entire year, Nicki ran a total of 520 + 780 = 1,300 miles. The answer is 1300.
