The box currently contains 46 coins, consisting of pennies, dimes, and quarters. The number of pennies is equal to the number of dimes, and the total value is $5.26. How many of each denomination of coin does he have?
The number of pennies, which is also equal to the number of dimes is...
The number of quarters is...

Question

anonymous · Answer

p + d + q = 46
p*1 + d*10 + q*25 = 526

In both equations sub p=d, so you'll have 2 eqns in p and q
Solve for p and q, and get d

anonymous · Answer

So you would multiply 46 by each one

anonymous · Answer

p + d + q = 46
2p + q = 46

p*1 + d*10 + q*25 = 526
11p+25q=526

So now you have 2 eqns and 2 variables. Can you solve that.

I very confused  on this problem. Do I solve both equations on the bottom or stop.

anonymous · Answer

Could you show me the steps

anonymous · Answer

Just solve these two and find p and q
2p + q = 46
11p+25q=526

anonymous · Answer

Use a calculator if you have one that can do equations

anonymous · Answer

I don't have one

anonymous · Answer

p=16, q = 14
d = p = 16
