Question

the cost of annual tution design at a university increased from 10,500 to $11,300. what is the percent increase in tution to the nearest tenth of a percent?

Answer 1

For this case we can make the following rule of three:
$ 10500 -------> 100%
$ 11300 -------> x
Clearing the value of x we have:
x = (11300/10500) * (100)
x = 107.6190476
The percentage of growth is:
107.6190476 - 100 = 7.6190476%
Round to the nearest tenth:
7.6%
Answer:
the percent increase in tution is:
7.6%
