Question 141401
working in cents to avoid decimal points


"two movies and three game for a total of $15.50" __ 2m+3g=1550


"three movies and one game for a total of $12.05" __ 3m+g=1205 __ g=1205-3m


substituting __ 2m+3(1205-3m)=1550 __ 2m+3615-9m=1550 __ 2065=7m __ 295=m


substituting __ g=1205-3(295) __ g=320
