At the beginning of October, Monique changed banks and decided to leave the remaining $3900 in her old checking account to pay for rent. After six months, her balance was finally zero. If the balance, B, in Monique’s account is a function of time, t, write an equation for the situation.

• B = 3900 – 650t

• B = 3900 + 650t

• B = 3900t – 650t

• B = 3900t + 650t

On a recent scuba diving trip, Kate and Kara reached a depth of 130 feet. Six-and- a-half minutes later after ascending at a constant rate, they reached the surface. Write an equation to represent their distance, D, as a function of time, t.

• D = 130 – 20t

• D = 130 + 20t

• D = 20 – 130t

• D = 20 + 130t
