Answer:

-5x + 7

Step-by-step explanation:

-4x - 2y = -2

x - 2y = 9

First, you're going to subtract the equations from each other.

(-4x - 2y = -2) - (x - 2y = 9)

Next, you need to get rid of the equal sign in both equations.

(-4x - 2y = -2) - (x - 2y = 9)

     +2       +2        -9      -9  

After you get rid of the equal signs, you will distribute the sign to the equation and then subtract everything.

-4x - 2y + 2 - x + 2y + 9

Now, combine the like terms.

(-4x -x) + (-2y + 2y) + (2 + 9)

Finally, calculate the terms and solve.

-5x + 7

If sales are $425,000, variable costs are 62% of sales, and operating income is $50,000, what is the contribution margin ratio?
Dmitry_Shevchenko [17]

In an internal operating income statement, the form is as such:

(1) Sales (or Revenue) - Total Variable Costs = Contribution Margin;

(2) Contribution Margin - Total Fixed Costs = Operating Income

and

(3) Contribution Margin Ratio = Contribution Margin/Sales

The first equation helps us out. Sales is the whole amount for this statement, or 100%. We know variable costs are 62% and the rest goes to the Cont. Margin.

100% - 68% = 32% (choice A)
