Answer 2

There were 80 questions in her home work.

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 =
`(62.5x)/(100)`

x =
`(50* 100)/(62.5)`

x =
`(5000)/(62.5)`

x = 80

Therefore, total number of questions in her homework were 80.
