Write h(x) = x2 - 6x + 3 in vertex form by following these
steps:
Step 1: Model x2 - 6x + 3 by placing tiles in the Product
section. First place the x- and -x tiles along the left
and top borders to form two sides of a square. Then
place the + tiles along the ends of the -x tiles.

The percentage mark down from $68 to $44.20 is 35%

Given:

Mark down price = Original selling price - (x% of Original selling price)

44.20 = 68 - (x/100 × 68)

44.20 = 68 - (68x/100)

44.20 = 68 - 0.68x

44.20 - 68 = -0.68x

-23.8 = - 0.68x

x = -23.8 / - 0.68

x = 35%

Therefore, the percentage mark down is 35%
