James went shopping for a new watch. The original price was $150. It was marked down to $110. What is the percent of decrease?

26.7% is the percent of decrease

Step-by-step explanation:

$150=100% price (starting og price)

110 = ? or x (discounted price)

We need to find what is the decrease from 150 to 110 in percentage

Use ratios to solve:

$150:100%

$110:x (unknown)

Cross multiply to find x

150 times x = 150x, and 100x110 = 11000

= 150x=11000

Lets get x all by itself to fully solve. We have to divide to get x by itself:

= 150x/150=11000/150 (divide 150 both sides always)

= 73.3,

Now we subtract 73.3 from 100 to get the decrease percentage

100-73.3=26.7 which is the percent of decrease
