We have a question: Cristian has 50 more black cookies in his cookie jar than white cookies. He eats half of the black cookies and 3/4 of the white cookies. If he initially had 80 white cookies, how many cookies are remaining within the cookie jar altogether?
And an answer: 85
So how you got the answer?
Cristian eats 3 / 4 * 80 = 60 white cookies from the jar, 3 / 4 of the total number of white cookies in the cookie jar. The number of white cookies remaining in the cookie jar is 80 - 60 = 20. In his cookie jar, Cristian also has 80 + 50 = 130 black cookies. He eats 1 / 2 * 130 = 65 black cookies from the cookie jar. He remains with 130 - 65 = 65 black cookies after eating half of them. In total, Cristian has 65 + 20 = 85 cookies remaining in the jar.

We have a question: Chad bought 6 packages of cat food and 2 packages of dog food. Each package of cat food contained 9 cans, and each package of dog food contained 3 cans. How many more cans of cat food than dog food did Chad buy?
And an answer: 48
So how you got the answer?
Chad's cat food total was 6 packages * 9 cans = 54 cans of cat food. Chad's dog food total was 2 packages * 3 cans = 6 cans of dog food. Chad had 54 cans of cat food - 6 cans of dog food = 48 more cans of cat food.

We have a question: Tim's cat bit him. He decided to get himself and the cat checked out. His doctor's visits $300 and insurance covered 75%. His cat's visit cost $120 and his pet insurance covered $60. How much did he pay?
And an answer: 135
So how you got the answer?
The insurance covers 300 * .75 = $225. So he had to pay 300 - 225 = $75. The cats visit cost 120 - 60 = $60. So in total he paid 75 + 60 = $135.
