Answer:

Up

Step-by-step explanation:

Here the easy rules to remember the orientation of the parabolas are

a) If x is squared it opens up or down. And its coefficient of {x^{2}[tex] is negative it opens down.b) If y is squared it opens side ways right or left. It its coefficient of [tex]y^{2}

Hence in our equation of parabola

y = x^ 2-4

x is squared and its coefficient is positive , hence it opens up towards positive y axis.

divide $17.85 by 85 to obtain 1% then multiply by 100 to obtain original price.

original price = $17.85 × \frac{100}{85} = $21
