Answer :
The rate is the same.
What is the proportional relationship?
Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.
The relation between charge and time is
(I) $15. 75 for 3 hours = 15.75/3 = 5.25
(II) $26. 25 for 5 hours = 26.25/5 = 5.25
Both have the same rate.
As time increases the charge by him also increases but they have the same rate so this is a direct proportional relationship.
