Answer 1

7 hours is the correct one

Answer 2

Answer: The required number of hours that Iris worked is 7.

Step-by-step explanation: Given that Iris charges $50 for her consulting services plus $60 for each hour she works. On one job, iris charged $470.

We are to find the number of hours that Iris worked on the job.

Let x represents the number of hours for which Iris worked on the job.

Then, according to the given information, we have

`50+60* x=470\\\\\Rightarrow 50+60x=470\\\\\Rightarrow 60x=470-50\\\\\Rightarrow 60x=420\\\\\Rightarrow x=(420)/(60)\\\\\Rightarrow x=7.`

Thus, the required number of hours that Iris worked is 7.
