Answer:
There were 80 questions in her home work.
Step-by-step explanation:
Let there were x problems in Rachel's homework.
Rachel solved 50 problems and scored 62.5%
Therefore, total equation that models this situation will be
Solved questions = Total question × percent scored
50 = (62.5%) of x
50 = [tex]\frac{62.5x}{100}[/tex]
x = [tex]\frac{50\times 100}{62.5}[/tex]
x = [tex]\frac{5000}{62.5}[/tex]
x = 80
Therefore, total number of questions in her homework were 80.
