You are going to buy some cable television ads. You can get 20 spots for $1200 or 80 spots for $3200 what is the percentage disc
Lesechka [4]

Answer:

  33 1/3%

Step-by-step 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.
