Helen has twice as many dimes as nickels and five more quarters than nickels the value of her coins is 4.75 how many dimes does she have?
More than 25.
Eighteen
Nickels = 6 Dimes = 2 Quarters = 9 (1/3N) + N + (3+N) = 17 2 1/3N = 14 N = 6
7 quarters and 11 nickles

19 Quarters & 11 Nickels Let X = number of quarters & Y = number of nickels So, X = Y +8 (8 more quarters than nickels) 0.25*X + 0.05*Y = 5.30 Substitute first equation for x into second equation: 0.25*(Y+8) + 0.05*Y = 5.30 0.25Y + 2 + 0.05Y = 5.30 0.30Y + 2 = 5.30 0.30Y = 3.3 Y = 11 nickels, so the number of quarters X = 19 We can check these values with the second equation: 0.25*19 + 0.05*11 4.75 + 0.55 = 5.30
Nickels = 6 Dimes = 2 Quarters = 9 (1/3N) + N + (3+N) = 17 2 1/3N = 14 N = 6
To make 60c, you can have no more than 2 quarters, because if you had 3 quarters that would make 75c, which is too much. So, you could make 60c with no quarters and some nickels, 1 quarter and some nickels, or 2 quarters and some nickels. If you have no quarters, you would need 12 nickels (12 x 5 = 60) if you had 1 quarter, you would need 7 nickels (7 x 5 = 35, 35 + 25 = 60) If you had 2 quarters, you would need 2 nickels (2 x 5 = 10, 25 x 2 = 50, 10 + 50 = 60) So, if you have to make 60c using quarters AND nickels, there are two different ways to do it: 1 quarter + 7 nickels 2 quarters + 2 nickels
