[Question]Tom's cat needs an expensive surgery. He has had pet insurance for 24 months that cost $20 per month. The procedure cost $5000 but the insurance covers all but 20% of this. How much money did he save by having insurance?
[Answer]The insurance cost 24 * 20 = $480. With insurance he pays 5000 * .2 = $1000 for the procedure. So he paid 1000 + 480 = $1480. So he saved 5000 - 1480 = $3520. The answer is 3520.

[Question]In her first term, Governor Sandoval gave twice as many commencement addresses as Governor Hawkins. Governor Sloan gave ten more commencement addresses than Governor Sandoval in the same amount of time. If Governor Sandoval gave 12 commencement addresses, how many commencement addresses did the three of them give altogether?
[Answer]Since Governor Sandoval gave 12 commencement addresses, twice the number that Governor Hawkins gave, Governor Hawkins gave 12 / 2 = 6 commencement addresses. The two of them gave 6 + 12 = 18 commencement addresses in total. Governor Sloan gave ten more commencement addresses than Governor Sandoval, a total of 12 + 10 = 22 commencement addresses. The three of them gave 22 + 18 = 40 commencement addresses. The answer is 40.

[Question]Jenna's doctor tells her that she should tan no more than 200 minutes a month. If she tans 30 minutes a day, two days a week for the first two weeks of the month, how many minutes can she tan in the last two weeks of the month?
[Answer]First find how many minutes Jenna tans each of the first two weeks: 30 minutes / day * 2 days / week = 60 minutes / week. Then multiply that number by the number of weeks to find how many minutes Jenna tans in the first half of the month: 60 minutes / week * 2 weeks = 120 minutes. Then subtract that time from the total time Jenna can spend tanning to find how many more minutes she can tan: 200 minutes - 120 minutes = 80 minutes. The answer is 80.

[Question]Marjorie works as a baker. Every day, she makes twice as many cakes as she did the day before. On the sixth day, she makes 320 cakes. How many cakes did Marjorie make on the first day?
[Answer]
As the number of cakes doubles each day, Marjorie must have made 320 cakes / 2 = 160 cakes on the fifth day. So on the fourth day, she must have made 160 cakes / 2 = 80 cakes. This means that on the third day, she made 80 cakes / 2 = 40 cakes. On the second day, she made 40 cakes / 2 = 20 cakes. So on the first day, she made 20 cakes / 2 = 10 cakes. The answer is 10.
