**PsyDAG**, Monday, April 11, 2011 at 2:38pmLet x = boxes of Pilot and y = boxes of Bic

x + y =120 therefore

x = 120 - y

17.99x + 7.49y = 1234.8

Substitute 120-y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
