Answer this question:Tom wants to visit Barbados. He needs to get 10 different vaccines to go and a doctor's visit. They each cost $45 and the doctor's visit costs $250 but insurance will cover 80% of these medical bills. The trip itself cost $1200. How much will he have to pay?
The medical cost comes out to 45 * 10 + 250 = $700. Insurance covers 700 * .8 = $560. So he has to pay 700 - 560 = $140. Added to the cost of the trip he has to pay 1200 + 140 = $1340.
The answer is 1340.

Answer this question:James is building a hall of mirrors. Three of the walls will be completed covered with glass. If two of those walls are 30 feet by 12 feet and the third is 20 feet by 12 feet, how many square feet of glass does he need?
First find the area of one of the long walls: 30 feet * 12 feet = 360 square feet. Then double that amount since there are two walls: 360 square feet * 2 = 720 square feet. Then find the area of the short wall: 20 feet * 12 feet = 240 square feet. Then add that area to the area of the two long walls to find the total area: 720 square feet + 240 square feet = 960 square feet.
The answer is 960.

Answer this question:You start a business selling charm bracelets. You spend $1 on the string for each bracelet and $3 on beads for each bracelet. You sell the bracelets for $6 each. If you sell 25 bracelets, how much profit will you make?

The answer is 50.
