Question

Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana's account can be

represented by the equation y = 25x + 125, where x is the number of weeks she has been mowing the lawn. What does the y-intercept of the graph
represent in this situation?

Answer 1

The y-intercept in the equation y = 25x + 125 represents the starting amount of $125 in Jana's savings account before she started earning money from mowing the lawn.

Step-by-step explanation:

The equation y = 25x + 125 represents the amount of money (y) Jana has in her savings account after x weeks of mowing the lawn. In this linear equation, the y-intercept is 125, which corresponds to the value of y when x is 0. Therefore, the y-intercept signifies the initial amount Jana had in her savings account before she started mowing the lawn. In other words, before she began her weekly lawn mowing, Jana already had $125 in her account.

Answer 2

Hi there! x would be 6 weeks..

Step-by-step explanation:

So here says that Jana earns $25 per week for mowing the lawn. But in “x” weeks, she earns $125...this means that you would have to divide 125 with 25 or 25 multiply by x to find the answer of x.

How much does 25 go to 100? Well it would be 5. So for $100 it would be 5 weeks. We also know that 25 is 1 week. So add 5 with 1. 5 plus 1 would be 6.

Therefore, for $125, Jana would have to work for 6 whole weeks.
