To represent Andre's savings mathematically, we can create a linear equation.

Andre starts with an initial amount of $15, and he deposits an additional $5 per week. Let $A(t)$ represent Andre's savings after $t$ weeks, where $t$ is the number of weeks. The equation is:

$A(t) = 15 + 5t$

Where:

• $15$ is the initial amount.
• $5t$ represents the total amount deposited after $t$ weeks, with $5$ being the deposit per week.

Would you like to compare this to Noah’s savings equation or solve related questions?

Here are some related questions:

1. How much will Andre save after 10 weeks?
2. After how many weeks will Andre save $100?
3. What is the total amount Andre saves in 6 months (assuming 4 weeks per month)?
4. Write Noah's savings equation and compare it to Andre's.
5. How many weeks will it take for Andre to have more savings than Noah?

Tip: Visualizing the equations with a graph can help compare savings over time!
