Question

In Mrs. Felton’s class, a student must read at least 4 hours per week to receive a reading grade of 100 for the week. Last week Lucy received a reading grade of 100. Which inequality represents the number of hours Lucy read last week, where r is the number of hours read per week?

Answer 1

`r \geq 4`

Explanation:

r = number of hours lucy read last week

lucy read (more than or the exactly) 4 hours

you know that she read more than or exactly 4 hours because she recieved a grade of 100, and 4 hours is the minimum requirement for 100
