On a family outing, Tyler bought 5 cups of hot cocoa and 4 pretzels for $18.40. Some of his family members would like a second serving, so he went back to the same food stand and bought another 2 cups of hot cocoa and 4 pretzels for $11.20.

Here is a system of equations that represent the quantities and constraints in this situation.

equation 1: `5c+4p=18.40`

equation 2: `2c+4p=11.20`

What does the solution to the system, `\left(c, p\right)`, represent in this situation?
