Wendy is planning a wedding reception for 440 people and has a budget of $2,500. a tray of appetizers costs $22 and feeds 10 people, and a pan of pasta costs $55 and feeds 18 people. if she purchases a total combination of 70 trays and pans of food, which system of equations would best represent the situation where "p" is the number of pans of pasta and "s" is the number of trays of appetizers?
a. 17p + 10s = 70 and 55p + 22s < 2,500
b. 17p + 10s = 70 and 22p + 55s < 2,500
c. 10p + 17s = 70 and 22p + 55s > 2,500
d. p + s = 70 and 55p + 22s < 2,500
