Question 74306 • FL-1200700-Mathematics for College Algebra MIS

Let x represent the number of quick washes and let y represent the number of premium washes. Which system of linear equations represents the situation?

Answer

5x + 8y = 775 and x + y =125

5x – 8y = 125 and x + y = 775

5x + 8y = 775 and x – y = 125

5x – 8y = 125 and x – y = 775
