Problem Solving:

1. In a Chemistry course, there will be five tests. To get a B, a total of 400 points are needed. You get scores of 91, 86, 73, and 79 on the first four tests. What scores on the last test will give you at least a B?

2. 2.) A car rents $13.95 per day, plus 10 cents per mile. You are on a daily budget of $76. What mileages will allow you to stay within the budget?

3. 3.) You are going to invest $20, 000, part at 12% and part at 16%. What is the most that can be invested at 12% in order to make at least $3, 000 interest per year?
