The total price would come out to $393.25
Since the price is before the discount the 15% will not be used in solving the equation at all. So you do part/ whole = percent/100 (the percent being the tip). Since you are looking for the total, the original price will be your part. You then multiply 78.65 x 100 then divide by the percentage (20) to get your answer.

Answer:
-3 and -2
Step-by-step explanation:
7x² + 19x + 21 = 4x² + 4x + 3
combine like terms:
3x² + 15x + 18 = 0
3(x² + 5x + 6) = 0
(x + 3)(x + 2) = 0
x = -3
x = -2
