Erin is taking a quiz.

She can miss some questions on her quiz

She has to earn at-least 80 on the quiz

The inequality is 80 ≤ 100 - 5q

By solving the inequality we get,

or, 5q + 80 ≤ 100

or, 5q ≤ 100 - 80

or, 5q ≤ 20

or, q ≤ 20/5

or, q ≤ 4

Therefore the correct answer is Option A , q ≤ 4

Hope this helps..!!

Thank You :)
