Okay, we are not all americans here, so we don't know what type of coins is there.
anyway, let's supose u have 2 type of coins,
first type worth x dollars, and the other y dollars, (ex: x=0.5 dollars and y = 0.2 dollars)
and the number of coins needed is a for the first type of coins and b for the second, our equation will be,
a*x+b*y=S (1)
where S=1.8 dollars in your question, and u put x, and y in their values.
and the other equation is
a+b=22; (2)
this is a system of 2 equations for 2 unknow, u should be able to solve it !

10 dimes= $1.00
2 quarters = $0.50
5 nickels = $0.25
5 pennies = $0.05
Totals:
22 coins = $1.80

Well, if you went to McDonalds and ordered a shake, and the cashier said, "that will be a buck eighty", what would you give the cashier? This isn't just math, it's life.

.05x 18 = .90
.50 x 1 = .50
.20 x 1 = .20
.10 x 2 = .20
-----------------------
22 coins = $1.80

You may be "blond and beautiful" but you should not be shouting it on Yahoo. Boasting is vulgar.
