Rose has to write five tests for her class, where each test has a maximum possible score of 100. She averaged a score of 80 on her first four tests. What is the maximum possible average she can get on all five tests?

#1**0 **

The sum of her first four test scores is 80*4=320

To get the maximum possible average of all five tests, she must score a 100 on her last test.

So we get \(\frac{320+100}{5}\), which is equal to 84.
