8k = 4/9
Divide 8 to both sides, or multiply by its reciprocal 1/8:
k = 4/9 * 1/8
k = 4/72
k = 1/18
Because the coefficient is zero, there will be no correlation
Your answer would be $130.50.
We can write a ratio of earnings to hours as 108.75:15. Then, to find 18 hours, we find 1 hour and multiply by 18:
108.75 : 15
÷ 15
7.25 : 1
× 18
130.5 : 18
So therefore your answer is $130.50, I hope this helps!
