The final price (what it is selling for) is $796.40
The markup is 10% of the original price (the dealer's cost) , meaning that it is 10% more.
We need to find the original price.
We write this as an equation
The original price *110% = final price
This is because the original price is itself (100%) added with 10%
Plug in the known final price
Original Price * 110% = 796.40
Convert 110% to a decimal because the other numbers- such as the final price are also decimal numbers.
Convert 110% to a decimal by moving the decimal point up 2 spaces ( basically dividing it by 100)
110% = 1.1
So it is now
Original price *1.1 = 796.40
Divide both sides by 1.1 to isolate our unknown, the original price
Original price = $724
Answer:

Step-by-step explanation:
-2x-5y=-3+2x
+2
-5y=2x+3
÷-5
y=-0.4x-0.6
7a+14 thats is the answer for the problem
Answer:
$100
Step-by-step explanation:
1.
Remember how 20% is equal to 1/5?
2.
$80 is equal to 4/5 of the origanal price (1/5 being the 20% we took off of it)
3. With that in mind, we could easily find 20% of the origanal price.
4. So we fallow the equation 4/5 ÷ 4
also equal to 80 ÷ 4
5. 80 ÷ 4 is 20
6. now add 20 to 80 to make 100
(100 being 100% and the 20% was added to find the original price)
