A right triangle :) to find the length of a missing side, you can use the pythagorean theorem (a^2 + b^2 = c^2)
For this case, the first thing we must do is define variables:
x: number of quarters
y: number of nickels
We now write the system of equations:
x + y = 68
0.25x + 0.05y = 13.40
Solving the system we have:
x = 50
y = 18
Answer:
they have:
quarters = 50
nickels = 18
The answer is 194 you have to carry on
