Harry is a stay-at-home father taking care of his two children. When he is not changing diapers or doing laundry, he can work online up to 18 hours in a day. Denote the number of hours he works by x. He receives a wage of $10 an hour up to 10 hours of work, and $15 an hour for every subsequent hour up to a maximum of 8 additional hours. He spends all the money he earns on food (y) which costs $1 per unit. Draw Harry’s budget constraint assuming that x and y are divisible.
