Y= 150
Start by using substitution.
Change x+y=375 to x=375-y
Substitute this into 1.25x+0.75y=393.75
1.25(375-y)+0.75y=393.75
Distribute the 1.25
468.75-1.25y+0.75=393.75
Add like terms (y)
468.75-0.5y=393.75
Subtract 468.75 to the right
-0.5y=-75
Divide by -0.5
y=150
Let the number be x
2x-16=42
2x=42+16
2x= 58
x=29

Answer:
1,352,078 ways
Step-by-step explanation:
In this question, we are to calculate the number of ways in which Mr Wonka can give his candy to a visitor.
This is a selection problem. Hence what we will be using is simply combination.
This is just a way of choosing 12 pieces of candy from a total of 23
Mathematically; 23C12 = 23!/(23-12)!12!
= 1,352,078 ways
