Y=mx+b
Y1-Y2/X1-X2
14-10/5-3 = 4/2 = 2
Plug in (3,10):
(10)=2(3)+b
Solve:
10=6+b
B=4
M=2
Let n be the total number of puffs. Now we can write:
![n=\frac{5}{9}n+\frac{1}{3}n+18](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B5%7D%7B9%7Dn%2B%5Cfrac%7B1%7D%7B3%7Dn%2B18)
Adding the fractional value of n, we get:
![n=\frac{5+3}{9}n+18](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B5%2B3%7D%7B9%7Dn%2B18)
Simplifying and rearranging gives us:
![n-\frac{8}{9}n=18](https://tex.z-dn.net/?f=n-%5Cfrac%7B8%7D%7B9%7Dn%3D18)
Therefore we can simplify to get:
![\frac{1}{9}n=18](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7Dn%3D18)
and finally
![n=18\times9=?](https://tex.z-dn.net/?f=n%3D18%5Ctimes9%3D%3F)
The fraction of the puff that are tuna is found from:
P(x) = 12x – 180
Given:
A company makes and sells charm bracelets.
The cost of producing x bracelets is represented by the function C(x) = 180 +
8x
The revenue earned from selling x bracelets is represented by the function
R(x) = 20x.
Explanation of terms:
For x bracelets,
Cost of production is C(x); C(x) = 180 + 8x
Revenue earned is R(x); R(x) = 20x.Profit made is P(x); P(x) is unknown
Profit made = Revenue earned – Cost of production
∴ P(x) = R(x) – C(x)
P(x) = 20x – (180 + 8x)
P(x) = 20x – 180 – 8x
P(x) = 12x – 180
The profit made from selling x bracelets is represented by the function
<em> P(x) = 12x – 180</em>
