You will get help much faster if you type in the name of the subject. Typing in I need help means you hope someone reads the question AND has the knowledge to answer your question. I just clicked on the question to see what it was.
Here is how you do the problem,
Let x = number of months
The money deposited to A will be 15*x at the rate of $15/month.
The money deposited to B will be 10x at the rate of $10/month.
The account for A in x months will be 200+15x.
The account for B in x months will be 300+10x. The problem states that at this time both accounts will be the same; therefore, set them equal to each other.
200 + 15x = 300 + 10x
Solve for x (I find 20 months).
How much will they be worth in 20 months?
200 + 15*20 = ?
300 + 10*20 = ?

Okay thank you! I understand now!

Answer 3

Money Mike is putting money in two savings accounts. Let x
represent the number of months and y
represent the balance. Account A started with $225, and account B started with $350. Money Mike deposits $15 in account A and $10 in account B each month. This system of equations represents the situation.

y=225+15x

y=350+10x

After a certain number of months, the accounts will have the same balance. What is that balance?
