Answer:

4 nickels

12 dimes

9 quarters

Step-by-step explanation:

x = number of nickels

y = number of dimes

z = number if quarters

0.05×x + 0.1×y + 0.25×z = 3.65

y = 3x

z = 2x + 1

0.05x + 0.1×3x + 0.25×(2x + 1) = 3.65

5x + 30x + 25×(2x + 1) = 365

35x + 50x + 25 = 365

85x = 340

x = 340/85 = 4

y = 3×4 = 12

z = 2×4 + 1 = 9
