So setting up an equation might make this problem easier so I did.
The first equation is 0.25x+0.10y=19.30
The second equation is x+y=94
I forgot what to do after that so I started playing around with numbers using the two equations, and I ended up getting 28 dimes and 66 quarters.
0.25 (66) + 0.10 (28) = 19.30
66+28=94

Answer:
B. x = 7, y = 4√2
Step-by-step explanation:
Drop a vertical from the upper left corner
This creates a rectangle and a 45-45-90 triangle
The bottom of the rectangle is 3
The legs of the triangle are 4
Therefor
x = 4 + 3
x = 7
For a 45-45-90 triangle
the hypotenuse = leg * √2
y = 4√2
