Notice the point R
is a vertex between two "vertical angles"

those two folks are also the same
so now, we have the left triangle has angle P equals to angle T on the other triangle
we also have the side on the left triangle of PR equals the side of TR on the other triangle, and those two verticals angles are equal to each other
does ASA ring a bell?
Y = -1/3x + 4 . 4 is the intercept -1/3x is the slope
Let x represent the total cost, so i have this equation:
x=5c+12. Hope it help!
1. Add x on both sides of the equation.
2. Subtract 5 from both sides of the equation.
3. Divide both sides of the equation by 3.
If these aren’t options, tell me the options for each dropdown in the comments and I can help further.
