Mrs. Benson has 184 math assignments left to grade.

Explanation:

Here we have , Mrs. Benson has graded 46 math assignments but has 80% of the assignments left to grade.We need to find Mrs. Benson has how many math assignments left to grade. Let's find out:

Let total Number of math assignments be x , So According to question 46 math assignments are graded & 80% are left i.e.

⇒
`x = 46+(80x)/(100)`

⇒
`x -(80x)/(100)= 46`

⇒
`(100x-80x)/(100)= 46`

⇒
`(20x)/(100)= 46`

⇒
`(x)/(5)= 46`

⇒
`x=230`

Now , Assignments left to grade is :

⇒
`230-46`

⇒
`184`

Therefore , Mrs. Benson has 184 math assignments left to grade.
