Front

What is the cost structure of hiring a plumber in the given scenario?

Back

The plumber charges $75 per hour plus a $100 house call fee.

Front

How do you represent the maximum budget for hiring a plumber using an inequality?

Back

The inequality is represented as 75h + 100 ≤ 325, where h is the number of hours.

Front

What does the variable 'h' represent in the context of hiring a plumber?

Back

The variable 'h' represents the maximum number of hours you are willing to pay the plumber.

Front

What is the first step to solve the inequality 75h + 100 ≤ 325?

Back

Subtract 100 from both sides to isolate the term with 'h': 75h ≤ 225.

Front

After isolating 'h' in the inequality 75h ≤ 225, what is the next step?

Back

Divide both sides by 75 to find h: h ≤ 3.

Front

What is the maximum number of hours you can hire the plumber without exceeding your budget?

Back

The maximum number of hours is 3.

Front

What does the inequality x ≤ 1000 represent in the context of credit cards?

Back

It represents that the limit on the credit card cannot exceed $1000.

Front

How do you express a budget constraint in mathematical terms?

Back

A budget constraint can be expressed as an inequality that limits spending based on income or available funds.

Front

What is the significance of the house call fee in the total cost calculation?

Back

The house call fee is a fixed cost that must be added to the variable cost of hourly charges.

Front

How can you determine if you can afford additional hours with a plumber?

Back

By adjusting the inequality based on your total budget and the fixed costs, you can calculate the maximum additional hours.
