Answer:

Total cost= 55 + 0.42*x

x= miles driven

Step-by-step explanation:

Giving the following information:

Bob's cost for his truck was $112.96 for 138 miles.

Carl's cost for his truck was $142.78 for 209 miles.

<u>To calculate the fixed cost and variable cost per mile, we need to use the high-low method:</u>

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

Variable cost per unit= (142.78 - 112.96) / (209 - 138)

Variable cost per unit= $0.42 per mile

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

Fixed costs= 142.78 - (0.42*209)

Fixed costs= $55

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

Fixed costs= 112.96 - (0.42*138)

Fixed costs= $55

<u>Finally, the cost equation:</u>

Total cost= 55 + 0.42*x

x= miles driven
