Well, honey, you've got yourself a math problem. To make 85 cents using those coins, you can have combinations like 1 fifty cent coin, 1 twenty-five cent coin, 1 five cent coin, and 1 five cent coin. That's just one way to do it, but there are multiple combinations you can come up with to make a total of 85 cents using those coins.
To make 85 cents using the fewest coins possible, you would need one 50-cent coin (a half dollar), one 25-cent coin (a quarter), and one 10-cent coin (a dime). This combination totals 85 cents.
To make 89 cents with 6 coins, you have to first realize that the "9" part of the cents is comprised of 5 cents and 4 pennies. Therefore, you have to have 4 pennies and 85 cents using 2 coins; impossible, since you would need 3 coins(if you had half-dollars) to make that amount: a half-dollar, quarter, and a dime. Basically, it's impossible with only coins worth 0.01, 0.05, 0.10, 0.25, and 0.50 of the currency(US$, I assume?)
3 quarters & 2 nickels
To make 85 cents using 6 coins, you can use 3 quarters (75 cents), 1 dime (10 cents), and 1 nickel (5 cents). This combination totals 85 cents while using exactly 6 coins.
To make 85 cents, you can use various combinations of coins. For example, you could use 3 quarters (75 cents) and 2 dimes (20 cents) for a total of 5 coins. Alternatively, using 8 dimes and 1 nickel also totals 85 cents with 9 coins. The exact number of coins depends on the denominations you choose to use.

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.

Three quarters and one dime total 85 cents. Each quarter is worth 25 cents, so three quarters equal 75 cents. Adding the 10 cents from the dime brings the total to 85 cents.

3 coins- 1 half dollar, 1 quarter, and 1 dime. 4 coins- 3 quarters and 1 dime.
Each Nickel is worth 5¢ so ... 17 nickels X 5¢ equal 85¢ ... 85 cents.
