Answer:
Given expression = −50x+100.
Let us understand the structure of the above expression.
Actually above expression is written in slope-intercept form.
y= mx+b, where m is the slope and in other words we call a slope " rate of change", and b is the y-intercept, we take b as fix value.
If we compare −50x+100 by slope-intercept form mx+b, we can see that coefficent of x is -50 there,
Therefore, m=-50.
So, the rate of change of the bank account balance(in dollars per month) = $50/month.
And because it is a negative 50, so we could say the rate of decrease per month is $50.
