Answer:
9 quarters, 12 nickels, and 15 dimes.
Step-by-step explanation:
Let's start by naming the number of quarters x.
That means that the number of nickels is x+3.
(There are three fewer quarters than nickels)
The number of dimes would be x+6.
(There are six more dimes than quarters)
We know the total number of coins is 36.
We can set up an equation.
quarters+nickels+dimes=36
x+x+3+x+6=36
Combine like terms.
3x+9=36
Subtract 9 from both sides.
3x=27
Divide both sides by 3.
x=9
There are 9 quarters.
Use given info to find the number of other coins.
9+3=12
There are 12 nickels.
9+6=15
There are 15 dimes.
