Write the equation for the problem below using $y = m x + b$ Yolanda's $400 monthly expense account is set up through an automatic teller machine (ATM). She withdraws funds, using the $35 Fast Cash Option. The equation describes the amount that remains in her account after she makes x withdrawals during the month.
A) $y = 35 x + 400$
B) $y = - 35 x + 400$
C) $y = - 35 x - 400$
D) $y = 400$
E) $y = 35 x - 400$

Question

Quizplus · Accepted Answer

The correct equation is $y = -35x + 400$, where $y$ represents the remaining balance, $x$ represents the number of $35 withdrawals, and $400 is the initial amount. Each withdrawal decreases the balance, hence the negative coefficient.
