a coin collection consists of nickels, dimes, and quarters, and has a total value of $3.30. there are three times as many nickels as quarters. how many of each kind are there if the number of dimes is three less than the average number of nickels and the number of quarters?

18 nickels, 9 dimes, and 6 quarters.

Step-by-step explanation:

Just use the guessing method. I started with 15 and then went to 18. and got it right. A nickel a worth five cents so 18 times 5 = 90 cents. 18/3 is 6 and 18+6=24. 24/2 is 12 and 12-3 is 9. A dime is worth 10 cents so 9 times 10= 90 cents. A quarter is worth 25 cents and 6 times 25=150. 150+90+90+330        If you get this right can i please have brainliest
