The Solution:
Given:
Plan A:
Each text sent or received cost $0.10.
If x=number of texts sent or received in a month, the total cost is:
Plan B:
Users pay a fixed charge of $12 and an additional $0.02 for each text sent or received. So, we have the expression for the total charges as:
Part (a)
Writing the inequality that shows that to use plan A is cheaper than using plan B, we have:
Part (b)
Solving the inequality in part (a) above, we have:
Dividing both sides by 0.08, we have:
Therefore, the correct answer is [option 2]
Answer:
==================================================
Explanation:
We simply add the expressions we are given, though we cannot combine the terms (as they aren't like terms). There's not much to show in terms of steps, though I guess you could have the following:
Adding 4 onto 2^x means we shift the 2^x curve up four units.
