Yvette wants to earn a profit of $360, then. That means she has to make a total of $480. 480 divided by 18 is 26 and 2/3. That basically rounds up to $26.67.
480 = 18x
360 = 18x - 120
120(3) = 18x - 120

You never showed the triangle
Answer:


Step-by-step explanation:
We have been given the equation:

And 
Second equation can be rewritten as:

We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:


Now substitute
in equation (1) we get:
