In a house, there are 16 cats. Two of them are white, and 25% of them are black. The rest of the cats are grey. How many grey cats are in this house?
Let's think: In this house, there are 16 * 25 / 100 = 4 black cats. If there are two white cats, that means that there are 16 - 4 - 2 = 10 grey cats in this house.. The answer is: 10.

Gary bought his first used car for $6,000. Gary borrowed the money from his dad who said he could pay him back the full amount over 5 years. Gary decided he would pay his dad back the full amount in 2 years. How much more is Gary spending per month to pay the loan off in 2 years instead of 5?
Let's think: A full year has 12 months. So 2 years is 2 * 12 = 24 months. The loan amount is $6,000 that he will repay in 24 months so 6000 / 24 = $250 per month. If he paid his dad back in 5 years that 5 * 12 = 60 months. $6,000 loan spread out over 60 months is 6000 / 60 = $100 per month. To pay it off in 2 years instead of 5, Gary is paying 250 - 100 = $150 more per month.. The answer is: 150.

Wally buys bears at the park. A bear is priced at $4.00 for the first bear and a discount of 50 cents per bear is given after that. How much does Wally pay for 101 bears?
Let's think: If the price of an additional bear drops by fifty after the first purchase, the price of each additional bear is $4.00 - $0.50 = $3.50. Since Wally bought 101 bears, he was charged fifty cents less on 101 - 1 = 100 bears. The total cost for the 100 bears is 100 * $3.50 = $350. For the 101 bears, Wally paid a total of $350 + $4 = $354.. The answer is: 354.

In a truck, there are 26 pink hard hats, 15 green hard hats, and 24 yellow hard hats. If Carl takes away 4 pink hard hats, and John takes away 6 pink hard hats and twice as many green hard hats as the number of pink hard hats that he removed, then calculate the total number of hard hats that remained in the truck.
Let's think:
If there were 26 pink hard hats and Carl took away 4 pink hard hats, the number of pink hard hats that remained is 26 - 4 = 22. John also took away 6 pink hard hats, leaving 22 - 6 = 16 pink hard hats in the truck. If John also took twice as many green hard hats as pink hard hats, he took 2 * 6 = 12 green hard hats. The total number of green hard hats that remained in the truck is 15 - 12 = 3. In the truck, after some are taken, there were 3 green hard hats + 16 pink hard hats = 19 hard hats in the truck. Altogether, 19 green and pink hard hats + 24 yellow hards hats = 43 hard hats remained in the truck.. The answer is: 43.
