Answer:

(5,1)

Step-by-step explanation:

4x + 7•(x /4-1/4) = -13

   -9x/4 = -45/4

   -9x = -45

Solve equation for the variable  x

 9x = 45

  x = 5

By now we know this much :

x = 5

   y = x/4-1/4

Use the  x  value to solve for  y

   y = (/4)(5)-1/4 = 1

Zielflug [23.3K]

Answer:

40%

Step-by-step explanation:

The first step is to calculate the unit selling price

= total sales/number of units

= 200,000/50,000

= $4

The unit variable expense can be calculated as follows.

= total variable expense/number of units

= 120,000/50,000

= $2.4

The contribution margin per unit can be calculated as follows

=selling price per unit- variable cost.

= $4-$2.4

= $1.6

Therefore the contribution margin ratio can be calculated as follows.

= $1.6/$4

= 0.4×100

= 40%
