Last month, Jennifer earned $143 for her after-school job. If she was paid $6.50 per hour, how many hours did Jennifer work? A.18 hours
B.20 hours
C.22 hours
D. 24 hours

22 hours.

Step-by-step explanation:

Using algebra:

6.5x = 143

6.5      6.5

   x  = 22

VUX = vertical line, undefined slope, represented by x = a number.
so look at ur points (3,-5)and a vertical line is represented by x = a number...so in ur points, the x value is 3, therefore, ur equation is :
x = 3x will always be 3 no matter what y is.
