To find out how many weeks it will take Jamie to save $176 in her account, we can set up the following equation based on her deposits:
- Initial amount: Jamie starts with $40.
- Amount added weekly: She adds $17 each week.
Let \( w \) represent the number of weeks. The total amount in her account after \( w \) weeks can be expressed as:
\[ \text{Total amount} = 40 + 17w \]
We want to find \( w \) when the total amount equals $176:
\[ 40 + 17w = 176 \]
Next, we subtract 40 from both sides to isolate the term with \( w \):
\[ 17w = 176 - 40 \] \[ 17w = 136 \]
Now, divide both sides by 17 to solve for \( w \):
\[ w = \frac{136}{17} = 8 \]
Thus, it will take Jamie 8 weeks to save $176 in her account.
