Let c is the cost of renting a canoe and t is the cost of renting inner tubes.
For the girls,
2c + 3t = 80
For the boys,
c + 7t = 95
Solving the system of equations, multiply the second equation by 2 and subtract them.
2c + 3t = 80
2c + 14t = 190
---------------
11t = 110
t = 10
Substitute t to either equations,
c = 95 - 7t
c = 95 - 7(10)
c = 25
Therefore, one canoe costs $25 (C.)

The circumference of a circle can be calculated as follows:
c =
Where r is the radius of the circumference.
So in our case:
c = yd.
