An employee who produces x units per hour earns an hourly wage of y = 0.40x + 9 (in dollars). Find the hourly wage for an employee who produces 3 units per hour.

Wouldn't it be

wage=.4*3 + 9

Yes, you are correct in your calculation.

To find the hourly wage for an employee who produces 3 units per hour, you can substitute the value of x = 3 into the equation y = 0.40x + 9.

So, plugging in x = 3 into the equation, we get:

y = 0.40(3) + 9
= 1.20 + 9
= 10.20

Therefore, the hourly wage for an employee who produces 3 units per hour would be $10.20.
