Question: Christine figures it would take a pint of paint to paint the front and back of 1 door in her house. She has 8 doors to paint. At the paint store, she can either buy 8 separate pints of paint for $8.00 a pint or a gallon of paint (which is the same as 8 pints) for a flat $55.00 How much money will she save if she buys the gallon of paint instead of 8 pints?
Answer: 8 pints of paint cost $8.00 each so they would cost her 8 * 8 = $64.00. 8 pints of paint cost $64.00 or she could buy a gallon of paint for $55.00. If she buys a gallon, she will save 64 - 55 = $9.00. The answer is 9.

Question: Hattie and her friend Lorelei are doing a jumping contest using a jumping rope. Hattie does 180 jumps in the first round, while Lorelei jumps 3/4 as many times as Hattie jumped. In the second round, Lorelei does 50 more jumps than Hattie. If Hattie managed to jump 2/3 times the number of jumps she did in the first round, calculate the total number of jumps the two did in the two rounds.
Answer: In the first round, Lorelei did 3 / 4 * 180 jumps = 135 jumps. In the second round, Hattie did 2 / 3 * 180 jumps = 120 jumps, while. Lorelei did 120 jumps + 50 jumps = 170 jumps. The total number of jumps for the two in both rounds is 170 jumps + 120 jumps + 135 jumps + 180 jumps = 605 jumps. The answer is 605.

Question: Adam has three more than twice as many tattoos as Jason has. If Jason has two tattoos on each of his arms and three tattoos on each of his legs, how many tattoos does Adam have?
Answer:
2 tattoos on each arm is a total of 2 * 2 = 4 tattoos. 3 tattoos on each leg is a total of 2 * 3 = 6 tattoos. Thus, Jason has 4 + 6 = 10 tattoos. Twice the number of tattoos that Jason has is 2 * 10 = 20 tattoos. Adam has 3 more than twice the number Jason has, or 3 + 20 = 23 tattoos. The answer is 23.
