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

A ramp rises 1.5 feet <em>for </em>every 18 feet of horizontal distance. Basically the <em>for</em> is what gives it away. You could also just go with the fact that the x variable normally goes left to right (horizontal) and y goes up and down (Rises and falls) which gives you the same thing. The 1.5 feet is y and 18 feet is x
Answer:
x=53
y=19
Step-by-step explanation:
3x + y-5
3(5)=15
15+y
