Question

When the Yakity 24/7 cell phone was first introduced, it cost $80. Because of improved technology and effective marketing, the latest version of the Yakity 24/7 costs only $20. What is the percentage decrease from the introductory price to the current price?

Answer 1

Original price of Yakity 24/7 cell phone = $80

Current price of the Yakity 24/7 cell phone = $20

Decrease = $60

Percentage decrease =
`(Decrease)/(Original price)`×100

$60/$80 × 100 = 75%
