A quarter is 2.5 dimes. 85 quarters x 2.5 = 212. 5 So that's 212 dimes and a nickel.
A set of half dollar quarter and dime is worth 50+25+10 = 85 cents. So, with an equal number of these coins the sum can only be a multiple of 85 cents. 15 dollars is not a multiple so cannot be so changed.
Oh, dude, let's do some math, like, for fun. So, 2 quarters is 50 cents, 2 dimes is 20 cents, and 3 nickels is 15 cents. Add them all up and you get... drumroll... 85 cents! Wow, what a thrilling total, right?
1 quarter (25¢) 3 dimes (55¢) 6 nickles (85¢) 15 pennies (100¢)
.82, .85, .88
6816 quarters would weigh about 85 pounds.
85 dimes = 85*10 cents = 85*10/25 quarters = 34 quarters.
4 quarters=10 dimes x quarters=85 dimes quarter=10/4 dimes x (10/4 dimes) = 85 dimes x= 85 dimes/(10/4 dimes) x=34 Answer: 34 quarters

2 quarters, 3 dimes, 1 nickel, 3 pennies. I worked it out by knowing that 3 pennies would be needed for sure (to get from 85 to 88), but not 8 pennies, since there's no 80 cent coin. Then just started working it out with quarters, then seeing how many dimes, and then nickels would work out to the six remaining coins.

I don't think that this can be done using current US coins. In Canada, however, there are at least three combinations: -- 80 cents, 17 dimes, 2 quarters and a two-dollar coin -- 85 cents, 9 dimes, 5 quarters and a two-dollar coin -- 90 cents 1 dime, 8 quarters and a two dollar coin
