Question 1165032
The grade in Ma. Elena’s history class will be determined completely by three tests, each worth 100 points. She scored 78 and 84 on the first two test, but still hopes to get an Excellent grade, which would require an average of 92. What’s the minimum score she can get on the third test?

can you solve using Polya 4step solution?
<pre>Minimum score on 3rd in order to get a 92 or above is, 114, which is NOT POSSIBLE since the MAXIMUM score on ANY test is 100.
A MAXIMUM score of 100 only gives her an 87 average. 
<b><u>BOTTOM LINE:</b></u> She CANNOT get an excellent grade!
