Question

Jerome's teacher gave him a homework assignment on solving equations. Since he's been thinking about saving for a used car, he decided to use the assignment as an opportunity to model a savings plan. He already has $500, and he plans to save $375 every month. To model the situation, he created this equation, where y represents the total amount saved for the car and x represents the number of months since he started saving: 500 + 375x = y. He then solved the equation to determine how many months he would need to save to have enough to purchase the car. Review his work and select the error.

Which of the following is the error in Jerome's work?
A) There is no error; his equation is correct.
B) He should have used 375 + 500x = y as the equation.
C) The error is in using "x" to represent the number of months.
D) Jerome should have used 375y = 500x as the equation.

Answer 1

The error in Jerome's work is that he should have used 375 + 500x = y as the equation.

Step-by-step explanation:

The error in Jerome's work is option B) He should have used 375 + 500x = y as the equation.

In the given scenario, Jerome plans to save $375 every month, and he already has $500. To model the situation, he created the equation 500 + 375x = y, where x represents the number of months since he started saving and y represents the total amount saved for the car.

Therefore, the correct equation should be 375 + 500x = y.
