Question 583103
2 is unknow i can list several possible answers
3q 10d 20n
2q 20d 5n
8q 7d 1n
.... soo many possibilities 
1 looks solvable
n=2d
if d=9 n=18 and thats $1.80...hmmm
1.75=.1d+.05(2d)
1.75=.2d
8.75=d
well this means this is a bogus question as u cant have 3/4 of a dime
both questions are a fail and waste of time
