B would be the correct answer, 300 is how much you have and 59.48 is how much you’ve spent. You cannot go over 300 and you also have x so the equation is b. 59.48 + x <= 300
Decay equation= P*(1-r)^t P= Principal amount= $30,000 r= rate=0.065 t= time (in years) =5 x=30,000(1-0.065)^5 The value of the car in 5 years is approx. $21,438
