Question 1175383: Lori's piggy bank has only pennies and nickels. If she has 66 coins worth $2.38, how many of each
type of coin does she have?
It asks for the equations and to solve it
At a recent concert, 1200 people purchased tickets for a total of $26,520. Reserved tickets were $32
each and general admission tickets were $20. How many of each type of ticket was sold?
I would show my attempt into doing it but I really don't know how to start it
THANK YOU SO MUCH

p how many pennies
n how many nickels
system%28p%2Bn=66%2Cp%2B5n=238%29
HOW do you want or need to solve this?

If you want to use substitution, decide if substitute for p or for n.
Here is doing it for p.

%2866-n%29%2B5n=238
and you can continue from here.

If you want TO LEARN (not simply collect the tutors answers), then

        P L E A S E

put ONE and ONLY ONE problem per post

and NEVER PUT more than ONE problem PER POST.

On coin problems,  see the lessons
    - Coin problems
    - More Coin problems
    - Solving coin problems without using equations
    - Kevin and Randy Muise have a jar containing coins
    - Typical coin problems from the archive
in this site.

Learn the subject from there.

For ticket problems, read the lesson
    - Using systems of equations to solve problems on tickets
in this site,  explaining and showing all basic methods of solving such problems.


From these lessons,  learn on how to solve such problems once and for all.
