Data Insights (DI) Butler 2023-24 Click here for Details ] A candy store sells 50 types of candies, each type costing one dollar per candy. No customer is sold more than one candy. The store accepts only one-dollar bills or green tokens issued by the store. Each token costs two dollars. If a customer buys one candy with a token, a one-dollar bill is returned to the customer as change. Every day, at the start of the day, the store keeps exactly 300 one-dollar bills and no green tokens in its cash register. On a particular day, 600 candies were sold. On that day, customers were twice as likely to have paid with one-dollar bills as with green tokens. In the table, select the number of one-dollar bills and the number of green tokens present in the cash register at the end. Make only two selections, one in each column.
