There are numerous types of part time jobs are available nowadays in order to earn money for the qualified workers. People can earn through part-time jobs without quieting their full-time opportunities.

How much does Percy earn each hour?

Correct option is C.

For the answer to the two questions above,

3x + 2y = 36.50.... (1)

2x + 5y = 50..... (2)

Then, Eliminating x from the two equations by subtraction:

First we multiply equation 1 by 2 and equation 2 by 1.

6x + 4y = 73

6x + 15y = 150

After that, Subtracting the two,

-11y = -77

y=-77/-11

y = 7

He earns $7 at the coffee cart.

Then, Substituting y into equation 1,

3x + 14 = 36.5

3(7)+14=36.5

x = $7.50

Therefore, he earns a greater wage of $7.50 at the library.
