1. **State the problem:** Kareem pays a monthly fee of 19 plus 0.07 per minute. The total charge is at least 94.39. We want to find the possible number of minutes $m$ he used. 2. **Write the inequality:** The total cost is $19 + 0.07m$. Since the least charge is 94.39, we have: $$19 + 0.07m \geq 94.39$$ 3. **Isolate the variable term:** Subtract 19 from both sides: $$\cancel{19} + 0.07m - \cancel{19} \geq 94.39 - 19$$ $$0.07m \geq 75.39$$ 4. **Solve for $m$ by dividing both sides by 0.07:** $$\frac{0.07m}{0.07} \geq \frac{75.39}{0.07}$$ $$m \geq 1077$$ 5. **Interpretation:** Kareem must have used at least 1077 minutes for his charge to be at least 94.39. **Final answer:** $$m \geq 1077$$
