Question

Find each percent of change 50.5 and 75

Answer 1

Answer: 48.5%

Step-by-step explanation:

The quantity 50.5 incresed to 75. The change in value is:

`75-50.5=24.5`

The change was 24.5, so we need to find what percentage of 50.5 is 24.5.

For this we can use the rule of three.

Quantity Percentage

50.5 ---> 100%

24.5 ---> x

this means that if 50.5 is the 100%, 24.5 is a percentage x. This percentage x is found using the rule of three by multiplying que cross quantities in the last table (24.5 by 100), and then dividing by the remaining amount (50.5).

Thus:

`x=(24.5\cdot100)/(50.5)=(2450)/(50.5)=48.5`

The percentage change between 50.5 and 75 is 48.5%
