sorry if im wrong.
It’s the same as graphing a linear function, you choose a value for x and plug it into the equation, do this several times so you know the general shape, and connect the dots, it should look like a parabola
Marked down 15% means the new price would be 85% of the original price ( 100%-15% - 85%)
Multiply the original price by 85%:
5250 x 0.85 = 4462.50
The new price is $4,462.50
