One year the postage rate for sending 1 ounce of mail first class was increased from 25 cents to 29 cents. The percent of increase in the 29 cent postage rate was most nearly?
29/25 * 100% = 116%
% increase = 116% - 100% =
To calculate the percent increase, you need to find the difference between the new and old values and divide it by the old value, then multiply by 100 to get the percentage.
First, let's find the difference between the new and old postage rates:
Difference = new value - old value
Difference = 29 cents - 25 cents
Difference = 4 cents
Next, divide the difference by the old value:
Percent Increase = (Difference / old value) * 100
Percent Increase = (4 cents / 25 cents) * 100
To simplify the calculation, convert both cents to dollars:
Percent Increase = (4 / 25) * 100
Now, divide 4 by 25:
Percent Increase = 0.16 * 100
Multiply 0.16 by 100:
Percent Increase = 16
Therefore, the percent increase in the 29 cent postage rate is approximately 16%.
This is a proportional situation
(increase value)/original amount = percent increase/total percent
(29-25)/25 = x/100
Solve for x
