Question

Chapter 3, Problem 10CA

To determine

An inequality that represents the number of monthsm you can pay your rent without receiving a text alert.

Expert Solution

Answer to Problem 10CA

3000−625m≥700

Explanation of Solution

Given:

Your bank offers a text alert service that notifies you when your checking account balance drops below $700. The balance is currently $3000. You only use your account for paying your rent (no other deposits or deductions occur). Your rent each month is $625.

Calculation:

Rent for 1 month is $625 .

Then, rent for m months is $625×m=$625m .

Therefore, the balance in bank account after paying rent for m months is $3000−$625m .

The minimum balance in bank account must be equal or above $700 in order to avoid text alert.

Thus, in order to avoid text alert the balance must be 3000−625m≥700 .

Hence, 3000−625m≥700 represents the number of months m you can pay your rent without receiving a text alert.

To determine

Maximum number of months you can pay your rent without receiving a text alert.

Expert Solution

Answer to Problem 10CA

You can pay your rent without receiving a text alert for a maximum of 3 months.

Explanation of Solution

Given:

Calculation:

Solving the inequality,

3000−625m≥700⇒3000−625m+625m≥700+625m⇒3000≥700+625m⇒3000−700≥700+625m−700

⇒2300≥625m⇒625m≤2300⇒m≤2300625⇒m≤3.68

From the value of m , it is observed that the maximum value of m is 3.68 .

Since, rent is paid monthly, so we have to consider only the whole number value of m and discard its decimal value. So, maximum value of m is considered as 3.

Thus, you can pay your rent without receiving a text alert for a maximum of 3 months

To determine

The months you can pay your rent without making a deposit

Expert Solution

Answer to Problem 10CA

You can pay your rent without making a deposit for June, July and August.

Explanation of Solution

Given:

Calculation:

You can pay your rent without receiving a text alert for a maximum of 3 months.

Then, starting from June you can pay your rent in June, July and August.
