, Percy works two part-time jobs to help pay for college classes. On Monday, he works
3 hours at the library and 2 hours at the coffee cart and earns $36.50. On Tuesday,
he works 2 hours at the library and 5 hours at the coffee cart and earns $50. His
hourly wage at the library, x, and hourly wage at the coffee cart, y, can be
determined using the system of equations below.
3x + 2y = 36.502x + 5y = 50.00
