Answer 2

33 1/3%

Explanation:

When you buy 20 ads, the per-ad rate is

$1200/20 = $60 . . . per ad

When you buy 80 ads, the per-ad rate is

$3200/80 = $40 . . . per ad

The percentage change to the $60 price is ...

((new price) - (original price))/(original price) × 100%

= ($40 -$60)/$60 × 100% = -20/60 × 100%

= -1/3 × 100% = -33 1/3%

The higher volume purchase comes with a 33 1/3% discount.
