Sam’s car needed new tires. He spent $200 for the tires and charged them on his credit card. The credit card company charged him 1.5% interest each month on the money. (The interest charge will make the $200 grow.) Write an equation Sam can use to calculate the total amount of money he would owe at the end of x months. [To type in an exponent use the ^ symbol. For example, the equation in #1 can be represented like y=3000(1+.085)^x instead of y=3000(1+.085)ˣ.]
