Question 59946
Alright, I'm here to help. To solve this problem you need to set up an equation. The t and c are going to be what are called your variables. First, we'll set up your equation by starting with the $50 starting fee. Since you don't know how many tubes you will need to rent, you will use your variable t (for the number of tubes) and mutiply it by $6.95 (the cost of each tube rental). Now, add the two fees together. You should have 50+6.95t so far. Remember that the variable always comes after the number you are multiplying it by. Each canoe costs 10.95 per three hours, so the number to put in the equation here is $10.95 multiplied by c. Put it all together now. You should have:

50+6.95t+10.95c

You can solve this equation further if you like, because you know how many canoes you will need by dividing the number of people, by the number of people who will fit in each canoe (9/3=3). So now you know that you need three canoes, and you can substitute 3 for the variable c.

50+6.95+10.95(3)=
50+6.95+32.85

There you go, your final answer is 50+6.95+32.85
