Q: Anna's mom gave her $10.00 to buy anything she wanted from the candy store. Anna bought 3 packs of chewing gum for $1.00 each, 5 chocolate bars at $1 each and 2 large candy canes for $0.50 each. How much money did Anna have left?
A: Anna bought 3 packs of chewing gum that were $1 each for a total of 3 * 1 = $3. Anna bought 5 chocolate bars that were $1 each for a total of 5 * 1 = $5. Anna bought 2 large candy canes that were $.50 each for a total of 2 * .50 = $1. The total amount spent was $3 + $5 + $1 = $9.00. Anna had $10 to start and spent $9.00 so she had $10 - $9.00 = $1.00 left. The answer is 1.

Q: Jamie is in a walking group with 4 other ladies. The ladies all walk 3 miles together. On top of that, Jamie walks an additional 2 miles per day for 6 days while her friend Sue walks half that amount in 6 days. If they walk this same route 6 days a week, how many miles do the ladies walk in total?
A:
There are 5 ladies total in the group. They all walk 3 miles a day for 6 days so 3 * 6 = 18 miles. Jamie walks an additional 2 miles per day for 6 days so 2 * 6 = 12 miles. Sue walks half the distance of Jamie so 12 / 2 = 6 miles. Together, the ladies walk 18 + 12 + 6 = 36 miles. The answer is 36.
