Answer the following question.
Gail has some bills in her wallet which amount to $100. She has four $5 bills and three $20 bills, and the rest are $10 bills. How many $10 bills are in her wallet?
Step-by-step reasoning process: Four $5 bills amount to $5 x 4 = $20. Three $20 bills amount to $20 x 3 = $60. So Gail's $5 and $20 bills amount to $20 + $60 = $80. Thus, her $10 bills amount to $100 - $80 = $20. Therefore, she has $20 / $10 = 2 $10 bills.
The answer is 2.

Answer the following question.
Carla works at a food bank and she currently has stocked up 2000 cans of food. One day, 500 people showed up and took 1 can of food each. Carla had to then restock 1500 more cans to keep up with demand. The next day, 1000 people showed up and took 2 cans of food each. Carla restocked again with 3000 cans of food this time. How many cans of food did Carla give away?
Step-by-step reasoning process: One day, 2000 - 500 = 1500 cans of food were left. It was then restocked to 1500 + 1500 = 3000 cans. 1000 * 2 = 2000 cans were taken the next day. 3000 - 2000 = 1000 cans were left. It was restocked once more to 1000 + 3000 = 4000 cans of food. Carla gave away 500 + 2000 = 2500 cans of food.
The answer is 2500.

Answer the following question.
Paul uses 1 can of frosting to frost a layer cake. He uses a half can of frosting for a single cake, or a single pan of brownies, or a dozen cupcakes. For Saturday, he needs to have 3 layer cakes, 6 dozen cupcakes, 12 single cakes and 18 pans of brownies ready and frosted for customer pick up. How many cans of frosting will he need?
Step-by-step reasoning process: He needs 1 can of frosting per layer cake and he needs to make 3 layer cakes so that's 1 * 3 = 3 cans of frosting. There are 6 dozen cupcakes,12 single cakes and 18 pans of brownies for a total of 6 + 12 + 18 = 36 orders. Each of the 36 orders needs 1 / 2 can of frosting so they need 36 * .5 = 18 cans of frosting. He needs 3 cans of frosting for the layer cakes and 18 cans for the remaining items for a total of 3 + 18 = 21 cans of frosting.
The answer is 21.

Answer the following question.
A spider has eight legs. If a group of spiders has 10 more spiders than half as many legs as a single spider has, what is the total number of spider legs in this group of spiders?
Step-by-step reasoning process: Half as many legs as a single spider has is 8 / 2 = 4 legs. 10 more spiders than half as many legs as a single spider has is 4 + 10 = 14 spiders. The total number of spider legs in a group of 14 spiders is 8 * 14 = 112 spider legs.
The answer is 112.
