The equations are dependent (they're the same equation).
If you multiply the bottom one by 5, you get the top one.
N=d-2
q=n+d =>q=(d-2)=q=2d-2
25q+5n+10d=525
replace q and n with d
25(2d-2) +5(d-2)+10d=525
50d-50+5d-10+10d=525
65d=585
d=9
n=7
q=16
56 + 32 = (8 x 7) + (8 x 4) = 8(7 + 4) (Answer C)
Total cost equals the yearly fee price plus $14 times number of hours.
T= total cost
n= number of hours
Equation:
T= $199 + $14n
Hope this helps! :)
