John just started a business making custom t-shirts.
To produce his t-shirts he takes the following steps:
Step 1: He meets each customer understand his/her personality. (1 hour)
Step 2: He creates a sketch and sends by email to his customer for review. (5 hours)
Step 3: He creates the template and prints the t-shirt by hand which takes about (3 hours) total.
He values his time at $15 and charges $15 for a t-shirt, which he isn’t sure is enough.
