A restaurant sells only two desserts,pie and cake.

A piece of pie cost $4.
A piece of cake cost $5.
The restaurant sells 100 desserts,which cost a total of $473.
How many pieces of pie did they sell (HELP NEEDED FAST)

Answer

Let p and c be the pieces of pie and cake respectively.
We have p+ c= 100 (because the total number of pieces of pie and cake is 100).
On the other hand, we have $4p+ $5c= $473 or 4p+ 5c= 473 p+c=100 4p+5c=473 Solving the set of equations above, we p= 27, c=73.
They sold 27 pieces of pie~
