Find the percent of increase.
50 to 70
a. 20%****
b. 30%
c. 40%
d. 50%
IncreaseInitial Value x 100 = Percent Increase (%)
Initial Value X = 50 & New Value Y = 70
Increase = (Y - X)
(70 - 50)50 x 100 = ?
Apply the values in the percentage increase {(Y - X)/X x 100} formula
= (70 - 50)50 x 100
= 2050 x 100
(70 - 50)50 x 100 = 40%
The percent of increase = ( 70 - 50 ) / 50 = 20 / 50 = 2 * 20 / 2 / 50 = 40 / 100 = 40%
20 = 50x
20/50 = x
0.4 = x
My typo.
The percent of increase = ( 70 - 50 ) / 50 = 20 / 50 = 2 * 20 / 2 * 50 = 40 / 100 = 40%
To find the percent of increase, you need to calculate the difference between the final value (70) and the initial value (50). Then divide that difference by the initial value and multiply by 100.
In this case, the difference between 70 and 50 is 20. Dividing 20 by 50 gives us 0.4, and multiplying by 100 gives us 40%.
Therefore, the percent of increase from 50 to 70 is 40%.
So, the correct answer is c. 40%.
