Problema Solution

You are planning a party for 230 people and you have $1500 to spend. A pan of pasta feeds 15 people and $45, while a sand which tray feeds 12 people and cost $35. How many pans of pasta and trays of sandwiches can you order to stay within your budget?

Answer provided by our tutors

let 'x' represent the number of pasta trays purchased and 'y' represent the number of sandwich trays purchased


230 = 15x + 12y

1500 = 45x + 35y

but this system has no reasonable solution, it appears that there are many possibilities


if all you bought was sandwiches:

1500/35 = 42 trays of sandwiches


42 * 12 = 504 people could be fed


similarly, for pasta, 500 people could be fed


so buying any combination of pasta or sandwiches will feet all 230 people with double the food leftover
