The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops.

Lady_Fox [76]

Answer:

$m(c(a)) = 4.8875a$

Step-by-step explanation:

The missing parameters are:

$c(a) = 4.25a$ --- Cost of marble countertops

$m(c) = 1.15c$ --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

$c(a) = 4.25a$

$m(c) = 1.15c$

$m(c) = 1.15c$ can be written as:

$m(c(a)) = 1.15*c(a)$

Substitute: $c(a) = 4.25a$

$m(c(a)) = 1.15*4.25a$

$m(c(a)) = 4.8875a$

Hence, the cost of marked up price is: $m(c(a)) = 4.8875a$
