At a tech company, employees retrieve coffee from a machine using two types of company-issued credits—blue credits and red credits. Each red credit is equal in value to 4 blue credits.
The ZX200 is a machine at the company that offers only one type of coffee at a price of 2 blue credits. If 1 red credit is inserted, 2 blue credits will be returned along with the coffee. Employees are equally likely to get a coffee from this machine with 1 red credit as they are with 2 blue credits. When the ZX200 is serviced, all credits are removed except for 150 blue credits. This is the only time credits are removed.
Between the last service and today, 500 coffees were retrieved from the ZX200. In the table, select the number of credits of each type that would be expected to be in the ZX200 today. Make only two selections, one in each column.
