For the past 4 weeks, you have saved $5 per week. You know have $65 in your savings account. Write an equation that represents your balance A after t weeks.
To write an equation that represents your balance A after t weeks, we can use the information given.
We know that for the past 4 weeks, you saved $5 per week. This means that for every week, you saved an additional $5.
In t weeks, you would have saved a total of $5 multiplied by the number of weeks, t. Therefore, the amount saved after t weeks can be represented by the equation:
A = 5t
Where:
A represents the balance in the savings account after t weeks, and
t represents the number of weeks.
In this case, since you currently have $65 in your savings account, you can substitute A with 65:
65 = 5t
This equation can help you determine how many weeks it took for you to accumulate $65. You can rearrange the equation to solve for t:
t = 65/5
t = 13
Therefore, it took you 13 weeks to save $65, considering you saved $5 per week for the past 4 weeks.
