Answer:
217
Step-by-step explanation:
The regular price of the TV is 500$
Its marked up 60% from that price.
The mark up is equal to 60% of $500 which is equal to .60 * $500 which is equal to $300
Discount is like a markdown, so subtract $300 from the price of the item before the change to get $500 - $300 = $200
This is the price of the item before tax is applied.
Now you apply the sales tax of 8.5%.
8.5% of $200 is equal to .085 * $200 which is equal to $17
Tax is like a markup, so add $17 to the price of the item before tax was applied to get a selling price of $200 + $17 which is equal to $217
In order to solve using elimination, we need to be able to get rid of one variable, so that we can solve for the other. We need to subtract these two equations given from one another, or multiply the bottom equation by a negative and add them together.
(-5x + 6y = 8) - (-5x + 4y = 2)
(-5x + 6y = 8) + (5x - 4y = -2)
0x + 2y = 6
2y = 6
y = 3
Now that we know the value of one variable, we can take that value and plug it back into one of the original equations and solve for the value of the other variable.
-5x + 6y = 8
-5x + 6(3) = 8
-5x + 18 = 8
-5x = -10
x = 2
The solution to this system of equations is (2, 3).
Hope this helps!! :)
