.
His point total on the first three (Avg. 90) was (3)(90)=270 points
For all eight tests to have an average 95, his point total was (8)(95)=760.
All test points- first three test points=last five test points:
760-270=490
He scored a total of 490 points on the last 5 tests, so his average was:
490/5=98
ANSWER: Rodney averaged 98 on the last five tests.
