// Write your function here:

function finalGrade(midterm, final, homework) {
  if ((midterm < 0 || midterm > 100) || (final < 0 || final > 100) || (homework < 0 || homework > 100)) {
    return "You have entered an invalid grade." 
} else {

} if(average >= 0 && average <= 59){

}else if (average >= 60 && average <= 69){

}else if (average >= 70 && average <= 79){
  return "C"
}else if (average >= 80 && average <= 89){
  return "B"
}else if (average >= 90 && average <= 100) {
  return "A"
}
}
console.log(finalGrade(50, 54, 45))

// Uncomment the line below when you're ready to try out your function
// console.log(finalGrade(99, 92, 95)) // Should print 'A'

// We encourage you to add more function calls of your own to test your code!
