Question

For one photography session, Dexter earns no less than $50, but no more than $100. Which inequality can be used to represent his earnings, e? A. e ≥ 50 or e ≤ 100 B. e > 50 or e < 100 C. 50 < e < 100 D. 50 ≤ e ≤ 100

Answer 1

To answer let e be the amount of Dexter's earning. From the given conditions, it is implied that this value should be equal or more than $50. Further, this amount should also be less than or equal to $100. Mathematically, this can be expressed as,
                                50 ≤ e ≤ 100
The answer is letter D.
