1 $ 3,480 2,380
2 3,670 2,480
3 3,850 2,580
4 3,980 2,610

10 3,120 2,260
11 2,960 1,650
12 3,240 2,250
Using the high-low method, total monthly fixed cost is calculated to be:
a. $296.
b. $224.
c. $460.
d. $162.
e. $552.

Fixed costs= 510

10 3,120 2,260

11 2,960 1,650

12 3,240 2,250

To calculate the fixed costs, we need to use the following formulas:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (4,400 - 2,960) / (2,620 - 1,650)

Variable cost per unit= $1.484536

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 4,400 - (1.484536*2,620)

Fixed costs= $510

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 2,960 - (1.484536*1,650)

Fixed costs= 510
