You must have 2 functions: one computes the average and the other finds the letter grade. The average function should return back a Real value and the letter grade function should return back a string. All input and output must occur in main(). Only find and display the letter grade for the average, not  each test score.

You must have 2 functions: one computes the average and the other finds the letter grade.
The average function should return back a Real value and the letter grade function should return back a string. All input and output must occur in main().
Only find and display the letter grade for the average, not  each test score.

ject's kinetic energy.
7. Test Average and Grade
Write a program that asks the user to enter
five test scores. The program should display
a letter grade for each score and the average
test score. Design the following functions in
the program:
. calcAverage-This function should ac-
cept five test scores as arguments and
return the average of the scores.
• determineGrade – This function should
accept a test score as an argument and
return a letter grade for the score (as a
String), based on the following grading
scale:
Score
Letter Grade
90-100
A
80-89
В
70-79
60-69
D
Below 60
