y= 32+33x where y is the amount charged and x is the time in hours

197=32+33x
165=33x
5=x

Final answer: 5 hrs

Answer:

5 hours.

Step-by-step explanation:

The initial fees of Ralph = $32.00

Plus he charges per hour fees = $33.00

Let Ralph did a job for x hours.

His earning was = $32 + $33x = $197

33x = 197 - 32

33x = 165

x = [tex]\frac{165}{33}[/tex]

x = 5 hours

Ralph's job took 5 hours.
