A bank charges $3 each time you use an out-of-network ATM. At the beginning of the month, you have $1500 in your bank account. You withdraw $60 from your bank account each time you use an out-of-network ATM.
Write and graph a linear equation that represents the balance in your account after you use an out-of-network ATM [tex]$x$[/tex] times.
Answer (2)
Answer and workings are in the attachment below.
The bank account balance after using an out-of-network ATM x times is represented by the equation y = 1500 − 63 x . The y-intercept is 1500 and the slope is − 63 , indicating a decrease in balance with each transaction. To graph this, plot the y-intercept and draw a line with a negative slope.
