11 dimes and 5 nickels.
Let D = the number of dimes Let N = the number of nickels 10D + 5N = 170 N = D + 10 10D + 5(D + 10) = 170 10D + 5D + 50 = 170 15D = 120 D = 120/15 D = 8 N = 18
There are 11 ways. The formula is (20-2x) N + (x) D for x = 0 to 10 20 nickels, no dimes 18 nickels, 1 dime 16 nickes, 2 dimes 14 nickels, 3 dimes 12 nickels, 4 dimes 10 nickels, 5 dimes 8 nickels, 6 dimes 6 nickels, 7 dimes 4 nickels, 8 dimes 2 nickels, 9 dimes No nickels, 10 dimes
Let the Number of Dimes be D, then the number of nickels = 73 - DBy value, 5(73 - D) + 10D = 580 : 365 - 5D + 10D = 580 : 5D = 215 : D = 43There are 43 dimes.
