Question

Ralph is an electrician. He charges an initial fee of $32, plus $33 per hour. If Ralph earned an $197 on a job, how long did the job take

Answer 1

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 2

5 hours.

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 =
`(165)/(33)`

x = 5 hours

Ralph's job took 5 hours.
