Question

In 1967, a

30-second Super Bowl commercial cost $40,000. 
In 2000, a 30-second commercial cost $1,800,000.  What was the percent of change in the cost of
a commercial?

Answer 1

($1,800,000 - $40,000)/$40,000*100

($1,760,000)/$40,000*100

44*100

4400% change

Answer 2

The percent of change in the cost of a commercial is 4400%

Explanation:

In 1967, a 30-second Super Bowl commercial cost $40,000 i.e the initial cost was $40000

In 2000, a 30-second commercial cost $1,800,000 i.e the final cost was $1800000

We know that,

`\text{Percentage change}=\frac{\text{Final Value - Initial Value}}{\text{Initial Value}}* 100\%`

`=\frac{\text{1800000 - 40000}}{\text{4000}}* 100\%`

`=\frac{\text{1760000}}{\text{4000}}* 100\%`

`=44* 100\%`

`=4400\%`

Therefore, the percent of change in the cost of a commercial is 4400%
