Q:

A restaurant chain had 15,250 locations in 1975. By 2000, there were 21,655 locations. What was the percent increase in locations over the 25-year period?

Accepted Solution

A:
To find the percent increase we must subtract 21,655 by 15,250. After we subtract 21,655 by 15,250 we get 6,405. Now we divide 6,405 by the number of restaurant chains we started with, which was 15,250. When we do the division we get .42. Now all you have to do is divide .42 by 100, which is 42. That means the increase was 42%.
