Answer:
y = $1.10x + $600
Explanation:
Step 1 : Variable Cost calculation
Variable Cost = ($11,600 - $7,200) ÷ (10,000 - 6,000)
= $1.10
Step 2 : Fixed Cost calculation
Total cost = Variable Cost + Fixed Cost
hence,
Fixed Cost = Total Cost - Variable Cost
= $11,600 - (10,000 x $1.10)
= $600
Step 3 : Cost formula for maintenance
Total cost = Variable Cost + Fixed Cost
therefore,
y = $1.10x + $600
where,
y = Total cost
x = Activity level
Using the high-low method, the cost formula for maintenance is : y = $1.10x + $600
