Answer:
20 cents/minute
Step-by-step explanation:
We need to convert both units
1 dollar is 100 cents
12 dollars * 100 cents/1 dollar = 1200 cents
1 hour = 60 minutes
1 hours * 60 minutes / 1 hour = 60 minutes
12 dollars/ hour = 1200 cents / 60 minutes
Simplify
20 cents/minute
Answer: A. 20 cents per minute
Unit rate given: $12 per hour
Conversion:
$1 = 100 cents
$12 = 1200 cents
1 hour = 60 minutes
Solving steps:
amount in cents/time in minutes = 1200/60 = 20 cents per minute
