A coffee shop charges two different prices depending on the size of the cup. The table shows the number of regular-sized coffees and the number of large-sized coffees purchased in the past 3 hours. The total earnings for hours 1 and 2 are given. Each regular-sized coffee costs the same price, and each large-sized coffee costs the same price. The system of equations can be used to represent the situation. Use the drop-down menus to complete each statement.
