New Berlin Corporation has annual fixed costs of $800,000, variable costs of $48 per unit, and a contribution margin ratio of 40
OLEGan [10]

Based on the variable costs and contribution margin, the unit sales price is $80 and the unit contribution margin is $32.

The sales volume in units needed to earn $600,000 is 43,750 units and the amount in dollar sales needed is <u>$3,500,000.</u>

<h3>What is the unit sales price and unit contribution margin?</h3>

The unit sales price can be found as:

= Variable cost / (1 - contribution margin ratio)

= 48 / (1 - 40%)

= $80

Unit contribution margin is:
= Selling price x Contribution margin ratio

= 80 x 40%
= $32

<h3>What is the sales volume required to earn $600,000?</h3>

In units, this amount is:
= (Fixed cost + income required) / Contribution margin

= (800,000 + 600,000) / 32

= 43,750 units

In dollar terms the amount needed is:

= Units needed x selling price

= 43,750 x 80

= $3,500,000

X = 5 and y = 8 plz help
Galina-37 [17]
Hi,

To solve this expression, use the inputs of the x and y values to calculate the expression and result with an output. 

x=5
y=8

Plug in values:

5 (5 + 2) + 5^(2) + 8 

Evaluate:

5 (5 + 2) + 5^(2) + 8  = 5 ( 7 ) + 5^(2) + 8 

5 (7) + 25 + 8 

35 + 25 + 8 

=68


Your final answer is 68.
