Question

You have $140 in a savings account and save $10 per week. Your fiiend has $95 in a savings account and saves $19 per week. How many weeks will it take for you and your friend to have the same balance?

Answer 1

Answer: 5 weeks

Explanation:

To find out how many weeks it will take for you and your friend to have the same balance, you can set up an equation based on your savings:

Let's call the number of weeks it takes for you and your friend to have the same balance "w."

For your savings:

Initial amount = $140

Weekly savings = $10

So, your savings can be represented by the equation:

Savings = 140 + 10w

For your friend's savings:

Initial amount = $95

Weekly savings = $19

So, your friend's savings can be represented by the equation:

Savings = 95 + 19w

Now, you want to find when these two savings amounts will be equal, so you can set them equal to each other:

140 + 10w = 95 + 19w

Now, solve for "w":

140 - 95 = 19w - 10w

45 = 9w

Now, divide both sides by 9 to solve for "w":

w = 45 / 9

w = 5

So, it will take 5 weeks for you and your friend to have the same balance in your savings accounts.
