Question

The manufacturing cost of a cell phone was $124. Sellers first marked up the cost by 20 percent. Sales were poor, so sellers decreased the markup to 15 percent. Calculate the old and new selling prices.

Answer 1

20% = 0.2
so the old price would be
$124* 0.2= Mark Up
So old price would be $124+Mark up
Could you solve for it?

Answer 2

well the 20% increase means you pay

P = 124 * (1+0.2) as the markup price

then discounting you pay

D = P*(1 - 0.15)

hope it helps
