y = 7 + 3x
y = 3x + 7
y = mx + b, therefore the y-intercept is 7.
3y =  6x + 12
y = 2x + 4
y = mx + b, therefore the y-intercept is 4.
 
        
             
        
        
        
Answer:
m(c(a)) = 4.8875a can be used to find the marked-up price of a marble countertop depending on the area
Step-by-step explanation:
We are given that The cost for the raw materials of marble countertops, C s can be represented by the function c(a) = 4.25a --------1
a =  area of the countertops. 
we are also given that The retail markup, m, can be represented by the function m(c) = 1.15c.
We are supposed to find  function can be used to find the marked-up price of a marble countertop depending on the area?
Marked up price function : m(c) = 1.15c.
Substitute the value of c form 1
Marked up price function of a marble countertop depending on the area:
m(c(a))=1.15(4.25 a)
m(c(a))= 4.8875 a
So, Option 1 is true
Hence m(c(a)) = 4.8875a can be used to find the marked-up price of a marble countertop depending on the area
