3x+4y = 375
6x+ 4y= 600
-------------------
6x-3x = 600 - 375
3x=225
x=225:3
x=75 cents
3*x+4y= 375
3*75+4y=375
225 +4y = 375
4y=375-225
4y=150
y=150:4
y=37,5 cents
the price is 75+37,5=112,5 cents for one bag of potato chips and one candy bar
If you're looking for "x"
x/3 = 3
x = 3*3
x= 9
But what say it again wit what is this
So far, you've only defined f(x). You haven't asked a question.
A and B are both 5 units from it
