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
Right 4 units and up 2 units :)
We are asked in this problem to simplify the statements written on the problem. In this case, we can start converting words into numbers into the function.
<span>
1) (3/x + 2/(x+2) ) /(3/(x+2) -2/x. We should note that the word quantity denotes a parenthesis is started and that a set of terms is grouped inside the parenthesis.
simplifying, we try to make a common denominator out of this terms.
numerator:
denominator is x*(x+2), so the make up of the numerator is 3*(x+2) + 2x / (x*(x+2).
</span>denominator: 3x - 2(x-2) / (x*(x+2). <span>
The denominator has the same set of denominators which may cancel out both denominators. Hence,we simplify
num/denom = 3x+6 +2x / 3x -4x +4 = 5x +6 / 4-x
