Hourly Wage

Section 1.9
Question 89

Part (a)

y = 10 + 0.75x

x = 10 + 0.75y

(x - 10)= 0.75y

(x - 10)/(0.75) = y

Let x = number of units produced per hour.

Let y = hourly wage

Is this right?

Part (b)

Let y = 24.25

24.25 = (x - 10)/(0.75)

I need to find x.

(24.25)(0.75) = x - 10

18.1875 = x - 10

18.1875 + 10 = x

28.1875 = x

The problem does not say to round off any decimal number. I will press forward to say that the number of units produced when the hourly wage is $24.25 is 28.

 

correct

 

It feels good to be right.
