Answer this question:Jenny decided to get a cat with her girlfriend. They agreed to split all the costs down the middle except for they would each buy their own toys for the cat. The adoption fee was $50, the vet visits cost $500 for the first year and the monthly cost of food was $25. She bought $200 in toys. How much did Jenny spend on the cat in the first year?
The total cost for food was 25 * 12 = $300. So their shared expenses were 300 + 50 + 500 = $850. So Jenny spent 850 / 2 = $425 on shared expenses. So the total cost she paid was 425 + 200 = $625.
The answer is 625.

Answer this question:John plays a game for 4 hours a day every day for 2 weeks. After all that time, he is only 40% done. He increased his playtime to 7 hours a day. How long until he finishes the game?
There are 7 * 2 = 14 days in two weeks. So he played 14 * 4 = 56 hours. That means the total length of the game is 56 / .4 = 140 hours. So he has 140 - 56 = 84 hours to beat the game. So it will take him 84 / 7 = 12 days to beat the game.
The answer is 12.

Answer this question:Dawn earns 48,000 a year in 12 equal monthly payments. Each month, she saves 10% of her salary. How much does she save each month?
Dawn earns $4,000 a month because 48,000 / 12 = 4000. She saves $400 a month because 4,000 x .1 = 400.
The answer is 400.

Answer this question:If Billy and Jenny each order a $20 steak along with a $5 drink, how much will Billy have to pay in tips if he wants to cover 80% of a 20% tip for the two of them?
First, we figure out the price per meal by adding the steak and the drink together, finding a cost of 20 + 5 = 25 per meal. Then we multiply this by 2, as there are two people eating, meaning a total cost of 25 * 2 = 50 for both meals. Then we find the total tip amount for a 20% tip, by multiplying 50 * .2 = 10. Then we find out what 80% of this tip amount is by multiplying the desired tip of 10 by .8, finding 10 * .8 = 8 dollars that Billy should contribute.
The answer is 8.
