Answer:
$3
Explanation:
We have to use linear function to determine the variable cost per unit.
Let, x = fixed costs, y = variable cost per unit
According to the question,
x + 50,000 y = $230,000 ........ (i)
As the fixed cost increases 25% due to additional facilities, the new equation will be -
(x*25%) + x + 60,000 y = $280,000
or, 0.25x + x + 60,000 y = $280,000
or, 1.25 x + 60,000 y = $280,000 ......... (ii)
Multiplying the equation (i) by 1.25 and the equation (ii) by 1, we can get,
1.25x + 62,500 y = $287,500 ...... (iii)
1.25x + 60,000 y = $280,000 ......(iv)
Subtracting equation (iv) from (iii), we can get,
2,500 y = $7,500
or, y = $7,500 ÷ 2,500
or, y = $3
Therefore, the budgeted variable cost per unit = $3
