4 Qs 12 Dimes 20 Nickles
d = q + 3; 10d + 25q = 345. 10(q + 3) + 25q = 345 ie 35q = 315 so q = 9 and d = 12. Check: 9 quarters = $2.25, 12 dimes = $1.20, total $3.45.QED
$3.45 $1.00 = 4 quarters $2.00 = 8 quarters $3.00 = 12 quarters $3.00 + $0.25 + $0.10 + $0.10

You would have to know the exact number of coins per denomination. Modern U.S. quarters weigh 5.67 grams. Dimes 2.27 grams. Nickels 5 grams.
16 % of the coins are dimes. 4 of a total of 25.
$3.45 $1.00 = 4 quarters $2.00 = 8 quarters $3.00 = 12 quarters $3.00 + $0.25 + $0.10 + $0.10
Each quarter is 25, and he has X quarters. Each dime is 10, and he has 2X dimes. Each nickel is 5. He has 12 coins in total, and all of the ones that are not quarters or dimes are nickels. Since quarters and dimes have to come in sets of 3, that's 12-3X. 25X + 10(2X) + 5(12-3X) = 120 25X + 20X - 15X + 60 =120 30X + 60 = 120 30X = 60 X = 2 He has 2 quarters, 4 dimes, and 6 nickels. To double check let's add them up: (2 * 25) + (4* 10) + (6 * 5) = 120
