Given:
500 to 50
Determine the percent of change.
Solution:
In order to determine the percent of change, we must first subtract 500 by 50, then divide the difference by 500.
= 500 - 50
= 450
= 450/500
=0.9
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.9)(100)
= 90%
Final answer:
D. 90% decrease
