Julio is paid 1.4 times his hourly rate for each hour he works over 30 hours in a week. last week he worked 35 hours and earned 436.60. write and solve an equation to find julios normal hourly rate, r. explain how you know that that your answer is reasonable. show work so i can understand.

Here r represents Julio's normal hourly rate,

∵ He is paid 1.4 times his hourly rate for each hour he works over 30 hours,

If he worked for 35 hours,

Then, the charge for first 30 hours = normal hourly rate × 30

= 30r,

Also, the charges for additional 5 hours = new hourly rate × 5

= 1.4r × 5

= 7r

Hence, the total earnings = 30r + 7r

According to the question,

30r + 7r = 436.60

Which is the required equation,

By solving,

37r = 436.6

⇒ r = = 11.8,

Hence, the normal hourly rate is 11.8 per hour.
