Answer:
The maximum number of hours can be spend on work is 4 hours
Step-by-step explanation:
Given as :
The fixed charge of an auto shop = $100
The labor charge of auto shop = $175 per hour
The maximum money to be spend = $800
Let The maximum number of hours can be spend on work = n hours
<u>According to question</u>
The maximum money to be spend = fixed charge of an auto shop + labor charge of auto shop per hour × maximum number of hours
Or, $800 = $100 + $175 × n
Or, $175 × n = $800 - $100
Or, $175 × n = $700
∴ n =
i.e n = 4
So, The maximum number of hours can be spend on work = n = 4 hours
Hence, maximum number of hours can be spend on work is 4 hours Answer
