Answer

Answer:

$y = 30x$

Explanation:

Step1: Determine the type of relationship

This is a linear relationship. The general form of a linear equation is $y=mx + b$, where $m$ is the slope (rate of change) and $b$ is the y - intercept.

Step2: Identify the slope and y - intercept

Isabella saves $30$ per week. So the rate of change (slope) $m = 30$. Since she starts saving from $0$ (no initial amount saved, so $b = 0$).

Step3: Write the equation

Substitute $m = 30$ and $b = 0$ into the linear equation $y=mx + b$. We get $y=30x+0$, which simplifies to $y = 30x$.
