Question: Tom decides to renovate a house. There are 3 bedrooms and each bedroom takes 4 hours to renovate. The kitchen takes 50% longer than each bedroom. The living room took twice as much time as everything else combined. How long did everything take?
Answer: The kitchen took 4 * .5 = 2 hours longer than the bedrooms. So the kitchen took 4 + 2 = 6 hours. The bedrooms took 3 * 4 = 12 hours. So the kitchen and bedrooms combined took 12 + 6 = 18 hours. The living room took 18 * 2 = 36 hours. So everything took a total of 18 + 36 = 54 hours. The answer is 54.

Question: A department store offers a 10% discount for the amount exceeding $100 of the customer's total charge. Jaco bought a pair of shoes for $74; 2 pairs of socks that cost $2 per pair; a bag that costs $42. How much will Jaco pay for those items?
Answer: Two pairs of socks cost $2 x 2 = $4. Jaco's total charge is $74 + $4 + $42 = $120. The amount that exceeds $100 is $120 - $100 = $20. So, Jaco has $20 x 10 / 100 = $2 discount. Therefore, Jaco will pay $120 - $2 = $118 for those items. The answer is 118.

Question: On Friday, Hank opened his used-bicycle store with a stock of bicycles, all fixed-up and ready to ride. Over the course of the day, he sold 10 bicycles and bought an additional 15 to fix up. On Saturday, he sold 12 bicycles and bought 8 more. And on Sunday, he sold 9 bicycles and bought 11 more. What was the net increase in the number of bicycles in stock in Hank's store over the three days?
Answer: He sold 10 + 12 + 9 = 31 bicycles. He bought 15 + 8 + 11 = 34 bicycles. He now has 34 - 31 = 3 more than at Friday's opening. The answer is 3.

Question: Jan's three-eyed lizard has 3 times more wrinkles than eyes, and seven times more spots than wrinkles. How many fewer eyes does the lizard have than the combined number of spots and wrinkles?
Answer:
Three times more wrinkles than three eyes is 3 * 3 = 9 wrinkles. Seven times more spots than wrinkles is 7 * 9 = 63 spots. Therefore, the combined number of spots and wrinkles on the lizard is 63 + 9 = 72 spots and wrinkles. Thus, the lizard has 72 - 3 = 69 fewer eyes than spots and wrinkles. The answer is 69.
