Question

miss jones started with $50 in her savings account. she added $100 each week. write an equation that represents this situation. mrs. reeds car is not starting. she needs to call a mechanic for some help. the call - out fee is $25 and the mechanic charges $75 per hour. write an equation that represents this situation.

Explanation:

Step1: Analyze Mrs. Reed's situation

The total cost is the sum of the call - out fee and the cost per hour. Let $x$ be the number of hours the mechanic works. The call - out fee is a fixed cost of $25$ and the cost per hour is $75$. So the cost $y$ is given by the equation $y = 75x+25$.

Step2: Analyze Miss Jones's situation

Let $x$ be the number of weeks. Miss Jones starts with $50$ and adds $100$ each week. So the amount of money $y$ in her account is given by the equation $y=100x + 50$.

Answer:

For Mrs. Reed: $y = 75x+25$
For Miss Jones: $y=100x + 50$
