Compute the rate of discount allowed on a lawnmower that lists for $168 and is sold for $105. The rate of discount allowed is 43 % (Round to two decimal places as needed.)

The rate of discount of a lawnmower is 37,5%

Step-by-step explanation:

Sale price formula is

S = p - rp

where S = sale price,

r = discount percentage rate

p = the original price.

Isolating r

r = (p-S) / p

r = ($168 - $105) / $168

r=0.375

r = 37,5%
