c. you want to buy a new phone for $150, and still have $500 left in your accounts afterwards. explain how to determine when you can buy the phone.
Answer
Explanation:
Step1: Let the initial amount of money be (x).
The amount of money after buying the phone is (x - 150).
Step2: Set up an inequality.
We want (x-150\geq500).
Step3: Solve the inequality.
Add (150) to both sides: (x-150 + 150\geq500+150), so (x\geq650).
Answer:
You can buy the phone when you have at least (650) dollars initially.
