Indigo and her children went into a restaurant and she bought $42 worth of hamburgers and drinks. Each hamburger costs $5.50 and each drink costs $2.25. She bought a total of 10 hamburgers and drinks altogether. Write a system of equations that could be used to determine the number of hamburgers and the number of drinks that Indigo bought. Define the variables that you use to write the system.

h + d = 10
5.5h + 2.25d = 42
