Question

a delivery company charges a $12 fee once - off plus $6 per month. a) write an equation for total cost b) find the cost after 8 months

Explanation:

Step1: Define variables and equation

Let $C$ = total cost, $m$ = number of months. The total cost is the one-time fee plus monthly cost:
$C = 12 + 6m$

Step2: Substitute $m=8$ into equation

Calculate the monthly cost first, then add the one-time fee:
$C = 12 + 6(8)$

Step3: Compute the total cost

Simplify the expression:
$C = 12 + 48 = 60$

Answer:

a) $C = 12 + 6m$
b) $\$60$
