Answer
Let2odintegers
(2n+1),(2n+3)
→(2n+1)+(2n+3)=44
⇒4n+4=44
⇒4n=40
⇒n=10
then,integerare
2n+1=21
2n+3=23
We are given that
Max's grade on the first math exam was a 94
so, first exam grade =94
His grade on his seond math exam was an 89
so, second exam grade =89
change in grade=(first exam grade)-(second exam grade)
change in grade=94-89
change in grade=5
Percentage = ( change in grade)/( first exam grade) *100
so, percentage is
so,
the percent of change in Max's grade to the nearest whole percentage was 5%..........Answer
