Answer:
K = -16/33
Step-by-step explanation:
For a problem like this, it is convenient to write the mixed number as an improper fraction:
-11/8 K = 2/3
Now, multiply the equation by the reciprocal of the coefficient of K.
K = (-8/11)(2/3)
K = -16/33
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!
