Answer:
![Selling\ Price = 12b(1.55)](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%2012b%281.55%29)
Step-by-step explanation:
Given
![Cost\ Price = \$12](https://tex.z-dn.net/?f=Cost%5C%20Price%20%3D%20%5C%2412)
![Selling\ Price = 55\%\ more](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%2055%5C%25%5C%20more)
Required
Write an expression for the selling price for b birdbaths
This selling price for 1 birdbath is calculated as:
![Selling\ Price = Cost\ Price + 55\% * Cost\ Price](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%20Cost%5C%20Price%20%2B%2055%5C%25%20%2A%20Cost%5C%20Price)
Substitute 12 for Cost Price
![Selling\ Price = 12 + 55\% * 12](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%2012%20%2B%2055%5C%25%20%2A%2012)
Factorize:
![Selling\ Price = 12(1 + 55\%)](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%2012%281%20%2B%2055%5C%25%29)
Express percentage as decimal
![Selling\ Price = 12(1 + 0.55)](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%2012%281%20%2B%200.55%29)
![Selling\ Price = 12(1.55)](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%2012%281.55%29)
For b birdbaths, the selling price is:
![Selling\ Price = 12(1.55) * b](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%2012%281.55%29%20%2A%20b)
![Selling\ Price = 12b(1.55)](https://tex.z-dn.net/?f=Selling%5C%20Price%20%3D%2012b%281.55%29)
<em>The options are not clear; However </em>
<em> answers the question.</em>
Answer:
Step-by-step explanation:
3x - 4y = -11
x - 2y = -5
Compare the coefficients of the variables.
The coefficients of the x terms, 3 and 1, are multiples of each other.
The coefficients of the y terms, -4 and -2, are also multiples of each other.
That makes it easy to eliminate either variable.
I'll eliminate the y variables. Multiply the second equation by -2, then add it to the first equation:
₋-2x + 4y = 10
3x - 4y = -11
--------------------
x + 0y = -1 , so x = -1.
Substitute -1 for x in either equation and solve for y:
3(-1) - 4y = -11
y = 2
(x,y) = (-1, 2)
Answer:
A=2,b=-3,c=-2
