Answer:
130 cents per minute
Explanation:
Convert dollars to cents.
Note that 1$ = 100 cents.
Note that 1 hour = 60 minutes.
Using Dimensional Analysis would be a great way to approach this question and see how each of the units convert.
(78 $/1 hr) ( 1 hr / 60 min ) ( 100 cents / 1 $)
= 130 cents per minute.
