1 Math 96 Final Exam Study Guide Exam will consist of problems from old exams, plus at least 5 problems similar to the following: Section Solve the following system of equations. If the system does not have a unique solution, x 2y = 10 2x + y = 0 2. Solve the following system of equations. If the system does not have a unique solution, 3x + y = 5 4x + 5y = Solve the following system of equations. If the system does not have a unique solution, x 4y = 4 2x + 8y = 8 4. Solve the following system of equations. If the system does not have a unique solution, 3x y = 2 3x + 5y = Solve the following system of equations. If the system does not have a unique solution, 3x 17 = y 4x + 3y = Solve the following system of equations. If the system does not have a unique solution, 7x + 4y = 20 4x + 3y = Solve the following system of equations. If the system does not have a unique solution, 4x + 9y = 8 6x = 22 5y
2 8. Solve the following system of equations. If the system does not have a unique solution, 0.15x 0.06y = 0.96 x + y = Solve the following system of equations. If the system does not have a unique solution, 0.3x + 0.9y = 6 0.6x 0.7y = Solve the following system of equations. If the system does not have a unique solution, 3y = x + 6 x 3y = 6 Section A dairy needs 235 gallons of milk containing 4% butterfat. How many gallons each of milk containing 6% butterfat and milk containing 1% butterfat must be used to obtain the desired 235 gallons? 12. Jill invested some money at 14%. She also invested $100 more than 2 times that amount at 11%. How much is invested at each rate if she receives $191 in interest after one year. 13. An investor bought 600 shares of stock, some at $7.00 per share and some at $1.25 per share. If the total cost was $2935, how many shares of each stock did the investor buy? 14. A grocer wants to mix two kinds of nuts. One kind sells for $2.20 per pound, and the other sells for $2.60 per pound. He wants to mix a total of 40 pounds and sell it for $2.50 per pound. How many pounds of each should he use in his new mix? 15. A cyclist travels 96 kilometers in 5 hours. For part of the trip he travels at 24 miles per hour, and for the rest of the trip he travels at 18 miles per hour. How long did he travel at 24 miles per hour? 16.
