Rodney drove 3 hours at an average speed of 53 miles per hour. How far did Rodney
drive?

The rate at which Charles amount increased will be given by:
Amount owe=$390
Payment=$10 
Number of payments=10
thus using the formula:
A=P(1+r)^n
plugging the values we get:
390=10(1+r)^10
solving for r we get
39=(1+r)^10
r=0.4425
thus the amount increased by 44.25%
