thanks how bout this..
A social networking site recorded that 80% of the people who became members of the site one month were between 30 and 40 years old. The equation below represents this information, where x represents the total number of people who became members of the site that month.

x = 0.8x + 72

How many people who became members of the site that month were between 30 and 40 years of age?

 112

 288

 360

 432

this is rather confusing and incorrectly written! x cannot be equal to .8x+72. so maybe you misread the question. maybe y=.8x+72?
