Answer:

$1,892.8

Explanation:

Variable cost per minute:

= Change in cost ÷ Change in minute

= (4,000 - $2,640) ÷ (480 - 170)

= 1,360 ÷ 310

= 4.39 per minute

Fixed cost:

= January total bill - (January minutes × Variable cost per minute

= 4,000 - (480 × 4.39)

= 4,000 - 2,107.2

= $1,892.8

Therefore, the fixed portion of the total cost is $1,892.8
