5 x 5 x 5 = 125

62 unit squares shaded in all

62 divided by 125 = .496 x 100 = 49.6 rounded off = 50%

The discount is what you save (removed from actual price) while sale price is what you have to pay after subtracting the discount from the regular price.

100% = 70 (divide in half)

50% = 35

100% = 80

10% = 8 (multiply by 3)

30% = 24

5% = 4

35% = 28
