spent $73 billion. what is the percentage rate of growth? (round to one percentage place.)

The percentage rate of growth from 2010 to 2011 is the 1237.3%

Explanation:

The percentage rate or growth for online advertising spend in 2011 compared to 2010 is obtained when calculating the following operations:

1. You must know what is the base figure you want to use to determine the percentage growth. In this case $5.9 Billion is the base figure you will use.

2. You want to know what is the figure with which you will determine the final growth. In this case is $73 billion.

3. You replace the values in the following formula:

percentage rate or growth =((   Final growth figure   )  ) x 100

                                                         Base figure

percentage rate or growth =((  73   )  ) x 100

                                                     5.9    

percentage rate or growth = 12.3728 x 100

percentage rate or growth = 1237.28

4. As you want to round your answer to one percentage place, then you round to .28 to .3 that is the next higher decimal number.

percentage rate or growth = 1237.3%

its kinda hard to answer this when we dont have all the information that we need.
