Answer:
20 dimes and 4 quarters
Step-by-step explanation:
So, a dime is 10 cents and a quarter is 25
So, let's say you have x dimes and y quarters
X+Y=24 (total amount of coins)
Also,
10x+25y= 300 (cents)
I just put the 3 dollars into cents
Now, you have a system of equations and we should solve it:
X+y=24 ----x=24-y
10x+25y=300
So substitute x in the 2nd equation
10(24-y)+25y=300
240-10y+25y=300
240+15y=300
15y=60
y=4
Now that you know the amount of quarters, you can just say that you will have 20 dimes since 24-4=20
So, 4 quarters and 20 dimes
Check:
20 dimes=2 dollars
4 quarters= 1 dollar
correct
