The answer is $12 for an Apple pie and $15 for a cherry pie.
To get this answer you need to use simultaneous equation.
Let’s first note down the facts we know-
a= Apple Pie and c= Cherry Pie
So,
3a + 2c = 66.............(1)
a + 4c = 72................(2)
To use simultaneous equation, we will multiple (1) by 2.
Therefore,
6a + 4c = 132........(1)
Then we will subtract (1) by (2). The answer we will get is,
5a = 60
Hence, a = 60/5 = 12
Now that we found a (Apple pie), we substitute it into (2) and find c.
12 + 4c = 72
4c = 72 - 12
= 60
c = 60 / 4 = 15
Therefore, Each Apple Pie = $12 and each cherry pie = $15
You could also cross check these values with equations (1) and (2).
Hope you find it helpful.
