One pie costs $4 for a piece. Each pie is having 3 pieces. During one hour the bakery can make 12 pies. Creating one pie costs the bakery $0.5. Considering the bakery would be able to sell all pie pieces, how much money would it make?
If the bakery can make 12 pies, this means there would be 12 * 3 = 36 pie pieces.
For all the pieces the bakery would make 36 * 4 = $144.
The cost of making 12 pies is 12 * 0.5 = $6.
That means the bakery would make 144 - 6 = $138.
