The ABC Company had its highest level of production in May when they produced 4,000 units at a total cost of $110,000 and its lowest level of production in November when they produced 2,500 units at a total cost of $87,500. Using the high-low method, the estimated variable cost per unit is $

$15

Explanation:

The computation of the estimated variable cost per unit by using high low method is shown below:

Variable cost per unit = (High total cost - low total cost) ÷ (Highest level activity  - lowest level activity)

= ($110,000 - $87,500) ÷ (4,000 units - 2,500 units)

= $22,500 ÷ 1,500 units

= $15

By applying the above formula we easily find the estimated variable cost per unit

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
