Ben just turned 16 and got his first job, earning $180 per week. He gives $20 to his parents each week to help pay for his car insurance and phone bill, and he keeps another $25 for spending money. He puts the rest of his income in his checking account, which already has $250 in it.
Which function describes Ben's checking account balance after t weeks?
B(t) = 250 + (180 - 20 - 25)t
Therefore, Ben's checking account balance after t weeks can be represented by the function:
B(t) = 205t + 250
