Question

Last November there were 620 comma 666 scheduled passenger flights in a certain​ country, and in November of 1996 there were 651 comma 829. Use a percentage to express the relative change. Use the second given value as the reference value.​ Also, write a statement describing the result.The relative difference between November of 1996 and last November is what percent

Answer 1

Absolute change refers to the simple difference in the indicator over two periods in time, i.e.

`\text{Absolute change}=\text{Value in Period 1}-\text{Value in Period 2}.`

Relative change refers to the absolute change as a percentage of the value of the indicator in the earlier period, i.e.

`\text{Relative change}=\frac{\text{Absolute change}}{\text{Value in Period 1}}\cdot 100\%.`

Now,

Value in Period 1 = 651,829

Value in Period 2 = 620,666.

Then

`\text{Absolute change}=651,829-620,666=31,163.`

`\text{Relative change}=(31,163)/(651,829)\cdot 100\%\approx 4.78\%.`

The ratio between the difference in amounts of passengers to the amount of passengers in November of 1996 is 4.78%.
