10 people are going canoeing/tubing. some people will tube, some will canoe. tubes are $7 each. canoes are $11 each. tubes hold one person. canoes hold three. if you want to spend exactly $50, how many canoes and tubes can you buy?

i know this is a linear combination question. the equation for the cost i figured is 7t + 11c = 50 (t for tubes, c for canoes)
