Step-by-step explanation:
Answer:
6hrs
Step-by-step explanation:
First, we have to put the information given to us about the money they earn into an expression
let x represent the number of hours Kini and Duke work and y represent the total amount of money they earn in a week.
y(kini) = 9x + 8
y(duke) = 7.5x + 17
Now we subtract the x values and the constant values
9x - 7.5x = 1.5x
17 - 8 = 9
Make these into an equation
1.5x = 9
Divide both sides by 1.5 so x(the number of hours the both work) can stand alone.

x = 6 hrs
