A company that makes trail mix uses 1 3/8 pounds of peanuts for every 2/3 pound of raisins. They make 245 pounds of trail mix using only peanuts and raisins. How many pounds of peanuts do they use?

To set up an equation correctly and ultimately calculate what is asked, it is important to understand the problem statement and the given values. We do as follows:

(11/8) / (2/3) = x/y

x = 33y/16

x + y = 245

x + 16x/33 = 245

1.48x = 245

x = 97.97 pounds peanuts
