Question: On an American flag, the first stripe is red and half of the remaining stripes are also red. Each flag has 13 stripes. John buys 10 flags. How many red stripes are there?
Answer: There are 13 - 1 = 12 stripes left. So there are 12 / 2 = 6 red stripes. So the total number of red stripes is 6 + 1 = 7 red stripes. So he has a total of 7 * 10 = 70 red stripes. The answer is 70.
[Question]A shop sells laptops at $600 each and a smartphone at $400. Celine buys two laptops and four smartphones for her children. How much change does she get back if she has $3000?
[Answer]The cost of the two laptops is 2 x $600 = $1200. The cost of the four smartphones is 4 x $400 = $1600. Thus, the total cost of all the items is $1200 + $1600 = $2800. Therefore, Celine gets a change of $3000 - $2800 = $200. The answer is 200.
Q: A dog runs through a field and is joined by a group of 4 cats. 2 rabbits join each cat and 3 hares join each rabbit. How many animals are running through the field?
A: A pair of rabbits join each cat so there must be 4 cats * 2 rabbits / cat = 8 rabbits. As 3 hares join each rabbit, there must be 8 rabbits * 3 hares / rabbit = 24 hares. Counting all the animals shows there are 1 dog + 4 cats + 8 rabbits + 24 hares = 37 animals running through the field. The answer is 37.
Question: Casey wants to decorate her toenails and fingernails. First, she wants to do a base coat on each nail, then a coat of paint and finally a coat of glitter on every nail. It takes 20 minutes to apply each coat and 20 minutes for each coat to dry before applying the next one. Assuming Casey's nails will be done when all coats have been applied and dried, how many minutes will it take her to finish decorating her fingernails and toenails?
Answer: Casey wants to paint her 10 toenails + 10 fingernails = 20 nails in total. First she wants to do a base coat which takes 20 minutes to apply + 20 minutes to dry = 40 minutes total for the first coat. It will take the same amount of time to do a coat of paint and let it dry and to do a coat of glitter and let it dry, 40 minutes x 3 different coats = 120 minutes total to paint her toenails and fingernails. The answer is 120.
