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.

Step-by-step explanation:
an object and its shadow create a right-angled triangle.
2 objects and their shadows create 2 similar right-angled triangles.
that means the angles are the same, and the side lengths of one triangle all correlate with the corresponding side lengths of the other triangle via the same factor.
so,
42 × f = 6
f = 6/42 = 1/7
the length of Joel's shadow is then
20 × f = 20 × 1/7 = 2.857142857... ft
Y=1x+3 because if the y intercept is 3 and it goes up 1 and right 1 you get a Parellel line to (7,7) and (3,3)
