Question

An electrician changes a flat fee plus an hourly rate for a service call. She changes a total of $94 For a 3-hour service call on Monday and $130 for a 5-Your service call on Tuesday. how much should she change for 2-hour service call?

Answer 1

$56 (might be wrong but thatś what I got)

Answer 2

flat rate is $40  + $ 18 per hour

3 hour = $18 x 3 = $54  + flat rate $ 40 = $ 94

5 hour = $ 18 x 5  = $90  + flat rate $ 40 = $130

2 hour = $ 18 x 2 = $ 36 + flat rate $ 40 = $ 76
