The first seven customers of the day at a small donut shop have checks of $1.25, $2.36, $2.50, $2.15, $4.55, $1.10, and $0.95, respectively.
Based on the number of customers served each day, the manager of the shop claims that the shop needs an average check of $1.75 per person to stay profitable. Given her contention, has the shop made a profit in serving the first seven customers?
