Angela slept 6.5 hours every night in December. She decided she should get more sleep and began sleeping 8.5 hours a night in January. How much more sleep did Angela get in January? Give the rationale and then the answer.
Let's think step by step. Angela slept 8.5 – 6.5 = 2 more hours each night in January. There are 31 days in December and January, so Angela 2 x 31 = 62 more hours sleep.. The answer is: 62.

Debelyn, Christel, and Andrena collect dolls. Debelyn had 20 dolls before she gave Andrena 2 dolls. Christel had 24 dolls before giving Andrena 5 dolls. After all the gifts, Andrena now has 2 more dolls than Christel, how many more dolls does andrena have now than Debelyn? Give the rationale and then the answer.
Let's think step by step. Debelyn had 20 - 2 = 18 dolls left after giving out 2 dolls to Christel. Christel had 24 + 2 = 26 dolls after receiving 2 dolls from Debelyn. Christel had 24 - 5 = 19 dolls after giving Andrena 5 dolls. So, Andrena has 19 + 2 = 21 dolls now. Therefore, Andrena has 21 - 18 = 3 more dolls than Debelyn.. The answer is: 3.

Joe buys 3 oranges, 7 juices, 3 jars of honey, and 4 plants at the market. The fruit costs $4.50 each, the juice was 50 cents each, the jars of honey were $5, and the plants were 2 for $18. How much does Joe spend at the market? Give the rationale and then the answer.
Let's think step by step. Joe spends 4.50 * 3 = 13.50 on oranges. Joe spends 7 * 0.5 = 3.50 on juice. Joe spends 3 * 5 = 15 on honey. Each plant costs 18 / 2 = 9 dollars. Joe spends 9 * 4 = 36 on plants. Joe spends a total of 13.50 + 3.50 + 15 + 36 = 68 dollars at the market.. The answer is: 68.
