Answer:

Step-by-step explanation:

a sandwich store charges $10 delivery fee and $4.50

b. what is the total cost for x sandwiches ?

           total cost equals the cost of the sandwiches plus the delivery fee

one sandwich cost $4.50    

x number of sandwiches cost        x times $4.50   or $4.50(x)

delivery fee = $10

total cost equals the cost of the sandwiches plus the delivery fee

                            total cost  =        $4.50(x)      +               $10

total cost  =  $4.50(x)  +  $10
