Answer:
26.7% is the percent of decrease
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
