A company sells a product. The profit increased to 25 percent of the cost from 20 percent of cost after adjusting to new selling price. The new price is $80 and the cost is not changed. What is the old price?

p(n) = 80
cost (n) = 80/1.25 = 64
p(o) = 64(1.2) = 76.80

cost=x
old selling price=1.2x
new selling price=1.25x
1.2x = (80x1.2)/1.25 = $76.80

Cost of produt = $x

Prevous profit = $1.2x

New profit = $1.25x

New profit = New selling price - Cost

1.25x = 80 - x
0.25x = 80
x = 320

Old profit = Old selling price - Cost
1.2(320) = Old selling price - 320
Old selling price = $64

80 = 1.25 Cost
Old SP = Cost *1.2 = 80*1.2/1.25 = 80*24/25=384/5 = 76.8

Not so fast :lol:

0.25x = 80 -x

x = 64

64 + 0.2 * 64 = 76.8
