    Answer:

    C (m) = 5 m + 0.45 m   is the expression for the cost of mailing the invitations in terms of the number of  m mailed  letters.  

    The cost of mailing 3000 invitations is $16,350.

    Step-by-step explanation:

    Let us assume the number of invitations mailed  = m

    Now, the cost of each invitation = $5.00

    So, the cost of m invitation = m x ( cost of each invitation) =  m ( $ 5)=  5 m

    Also, the postage charges of each letter = $0.45

    So the postage charges of m letters sent  = m x( Cost of each letter) = 0.45 m

    Now, Total cost for mailing m Invitations

    =  Cost of m invitations +  Cost   of mailing m letters

    = 5 m + 0.45 m

    ⇒ C (m)  = 5 m + 0.45 m   …..  (1)

    This is the expression for the cost of mailing the invitations in terms of the number of mailed letters.

    Now, the cost for mailing 3000 invitations:

    Put m = 3000 in (1), we get:

    C(3000) = 5 (3000) + 0.45(3000) = 15,000 + 1350 = 16,350

    or, the cost of mailing 3000 invitations is $16,350.
