Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks. Jackie has $2363 in her retirement account, and Edgar has $2359 in his. Jackie is adding $9 per day, whereas Edgar is contributing $11 per day. Eventually, the two accounts will contain the same amount. How long will that take? What balance will each account have? After days, Jackie and Edgar will each have a retirement account balance of $□.
Q. Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks. Jackie has $2363 in her retirement account, and Edgar has $2359 in his. Jackie is adding $9 per day, whereas Edgar is contributing $11 per day. Eventually, the two accounts will contain the same amount. How long will that take? What balance will each account have? After days, Jackie and Edgar will each have a retirement account balance of $□.
Define Variables: Let's define the variables:Let x be the number of days after which both Jackie and Edgar will have the same amount in their retirement accounts.Let y be the amount of money that both Jackie and Edgar will have in their retirement accounts after x days.
Write Equations: We can write two equations to represent the situation:For Jackie: y=2363+9x (since she starts with $2363 and adds $9 per day)For Edgar: y=2359+11x (since he starts with $2359 and adds $11 per day)
Use Substitution: Now we will use substitution to solve the system of equations. Since both equations equal y, we can set them equal to each other: 2363+9x=2359+11x
Solve for x: Next, we solve for x:2363+9x−9x=2359+11x−9x2363=2359+2x2363−2359=2x4=2xx=24x=2
Find Value of y: Now that we have the value of x, we can find the value of y by substituting x into one of the original equations. We'll use Jackie's equation:y=2363+9(2)y=2363+18y=2381
Final Result: So, after 2 days, Jackie and Edgar will each have a retirement account balance of $2381.
