Question

ursula earns $9 per hour. to write an expression that tells how much money ursula earns for h hours, josh wrote 9\h. sarah wrote 9h. whose expression is correct and why

Answer 1

The important information's already given in the question can be used to find the correct answer.
In 1 hour Ursula earns = 9 dollars
So
In h hours Ursula earns = (9/1) * h dollars
                                       = 9 * h hours
                                       = 9h hours
So we have found from the above discussion that Sarah wrote the correct answer and it was 9h. I hope you are satisfi3ed with the answer and the explanation that I have provided. You can use this procedure for solving similar problems.

Answer 2

Sarah is correct because if Ursula is earning $9 per hour then every hour you can add 9. Lets say h=2 then you would multiply 9*2 to get how much she spent. Josh is incorrect because dividing would subtract the amount of money every our.

Hope this Helps
