A savings account balance can be modeled by the graph of the linear function shown on the grid.

(0,50) (1,150) (2,250) (3,350) (4,450)

What is the rate of change of the balance with respect to the number of deposits?

$100 per deposit 
$50 per deposit 
$0.50 per deposit 
$2 per deposit

The rate of change of the balance with respect to the number of deposits can be calculated by finding the slope of the linear function.

First, we need to determine the change in balance corresponding to the change in the number of deposits. From point (0,50) to point (1,150), the balance increases by $100.

So, the rate of change of the balance with respect to the number of deposits is $100 per deposit.
