1. This problem has no solution. In order to have $1.75 consisting of only dimes and nickels, you have to have an odd number of nickels. But no matter how many dimes you have, twice as many is an even number. You cannot simultaneously have an odd number of nickels and an even number of nickels.

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
