You start a bank account with $50. each week after that, you deposit $12. how many weeks will it take to have $230 in the account? a. 15 b. 8 c. 24.3 d. 10

You can solve this by writing an equation.
Start with 50, as you know you have that in your account, then add the variable x, to represent weeks, times 12, because you deposit 12 dollars a week. So your deposits will be shown by 50 + 12x. Now, since you want your deposits to equal $230, your should add that to your equation to make

50 + 12x = 230.

Now solve for x, or the number of weeks.

50 + 12x = 230            Subtract 50 from both sides
        12x = 180            Divide both sides by 12
            x = 15

It will take A) 15 weeks to have $230 in the account.

The expression of this would be 3.75x+y= 23
