X = D/(1 - h)
1 - h = D/x
h = 1 - D/x
D = 400, X = 4000
h = 1 - 400/4000
h = 1 - 0.1 = 0.9
The missing piece is the key to the unfinished puzzle
Answer:
50 % increase
Step-by-step explanation:
To find the percent increase, we take the new price and subtract the original price. Divide it by the original price
percent increase = (new - original)/ original * 100%
= (90-60)/60 * 100%
= 30/60 *100%
=.5 *100%
=50%
