How many ways can you make fifty cents using coins only?
51
You have 43 cents using only 8 coins what are the coins?
You can make 43 US cents using three dimes, two nickels, and three cents. (3 x 10) + (2 x 5) + (3 x 1) = 43
How many ways can you make 50 cents by only using 5 cents 10 cents 20 cents?
Oh, what a happy little question! You can make 50 cents using 5 cents, 10 cents, and 20 cents in three ways. You can use two 20 cent coins, one 20 cent coin and two 5 cent coins, or five 10 cent coins. Isn't that just delightful? Remember, there are no mistakes, just happy little accidents!
How can you make 30 cent with only two coins and one of them is not a nickel?
25 cents plus 5 cents = 30 cents. One of these coins is not a nickel.
How can you make 89 cents with 6 coins?
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?)
