Here is the answer with my work !!
81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
She sold 5 large bracelets.
3(x^2+10x+5)-5(x-k)=
3x^2+30x+15-5x+5k=
3x^2+25x+15+5k
for this to be divisible by x every term must include x or get eliminated
the problematic terms are 15 and 5k
to eliminate them they must equal 0 when added:
15+5k=0
5k=-15
k=-3
so A) -3 is the solution
The equation would be 60h=m
