Question

ah

Answer 1

p + n = 57 --> n = 57 - p
.01p + .05n = 1.85

now sub 57 - p in for n in the 2nd equation and you will find how many pennies thee are.

Answer 2

typo..*there

Answer 3

if you put say \(x\) as the number of pennies, then since the total is 57 coins that means the number of nickels is \(57-x\)
then since each nickel is worth 5 cents the total amount of money is
\[x+5(57-x)\] which you know is \(185\) cents
solve
\[x+5(57-x)=185\] for \(x\)
