Question

Angel is trying to save up to buy a new iPhone. He currently has 10$ in his piggy bank. He decides to mow lawns to make money for his new phone He makes $30 per lawn. White an equation to model this situation.

Answer 1

Step-by-step explanation:

There are two ways to approach this, depending on whether you want to track the total amount of money earned or the amount needed to reach the goal:

1. Tracking Total Earnings:

Let x be the number of lawns mowed.

Angel starts with $10 and adds $30 for each lawn mowed. So, the equation for the total earned is:

Total = 10 + 30x

This equation calculates the total amount of money Angel has after mowing x lawns.

2. Tracking Amount Needed:

Let y be the amount Angel needs to save to buy the iPhone.

Currently, Angel is y - 10 dollars short of the goal (since he has $10). So, the equation for the amount needed is:

Needed = y - 10

Angel earns $30 for each lawn mowed, so he reduces the amount needed by 30 each time. Therefore, the equation becomes:

Needed = y - 10 - 30x

Choose the equation that best fits your specific needs for modeling the situation.

Remember, both equations are valid approaches!
