Joe has a collection of nickels and dimes that is worth 6.05 If the number of dimes was doubled and the number of nickels was decreased by 10 the value of the coins would be 9.85 How many dimes?
dime = 0.10 nickle = 0.05 (1) 0.10d + 0.05n = 6.05 (2) 2x 0.10d + 0.05(n-10)=9.85 0.20d + 0.05n - 0.5 = 9.85 0.20d + 0.05n = 10.35 To make things easy, I'll multiply everything by 100 (1) 10d + 5n = 605 (2) 20d + 5n = 1035 (1) 5n = 605 - 10d n = 121 - 2d (2) 5n = 1035 - 20d n = 207 - 4d 121 - 2d = 207 - 4d 121 + 2d = 207 2d = 86 d = 43 43 Dimes
A stack of nickels and dimes is worth 2.55 Find the number of nickels if the number of dimes is12 less than twice the number of nickels?
Let N be the number of nickels. The value of nickels is 0.05N and the value of dimes is 0.10(2N-12). We can form the equation 0.05N + 0.10(2N-12) = 2.55 and solve for N. After solving, we find that there are 9 nickels.
