Answer 1

Answer:

• x < 18

Explanation:

1. Current cost

• $175 per month

2. New plan's cost

• $94 + $4.50 per device ⇒ 94 + 4.5x

3. Number of devices, x, for which the cost of the new plan is less than the cost of the current plan

• 94 + 4.5x < 175

4. Solve the inequality

• Subtract 94 from both sides:

        4.5 x < 175 - 94

         4.5x < 81

• Divide both sides by 4.5:

         x < 18

5. Answer: x < 18

The cost of the new plan is less than the cost of the current plan when the number of devices is less than 18; this is, maximum 17 devices.
