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.)
Answer:
$9 x 36 = $324, so choice #2
Step-by-step explanation:
They are not all squares because a rhombus has all sides of equal length, but NO right angles. A square is a rhombus WITH right angles.
Hope that clears things up.

Let a = Imani's weekly allownace
She spent half of her allowance, so she has half it left = a/2. She got $4 more from washing the car, so she has a/2 + 4 dollars which totals $12:
a/2 + $4 = $12
a/2 = $8
Solve for a.
