Compact discs (CDs) cost $12 each at the Music Emporium. The company charges $4.50 for shipping and handling, regardless of how many compact discs are purchased.

1    $16.50

2    $28.50

3    $40.50

$4.50 + $12c

$100.50

Step-by-step explanation:

Please find attached the complete question

Total cost in dollars = fixed cost + (variable cost x number of CDs bought)

fixed cost = $4.50

variable cost = $12

number of cds bought = c

total cost in dollars = $4.50 + $12c

total cost in dollars when 1 cd is bought = $4.50 + $12(1) = $16.50

total cost in dollars when 2 cds are bought = $4.50 + $12(2) = $28.50

total cost in dollars when 3 cds are bought = $4.50 + $12(3) = $40.50

total cost in dollars when 8 cds are bought = $4.50 + $12(8) = $100.50
