Carlos won 83 lollipops playing the bean bag toss at his schools game night. later, he gave three to each of his friends. write an expression for how many lollipops carlos has now.

y = 83 - 3x
where:
y is the number of lollipops left
x is the number of friends he has

Explanation:
Assume that the number of lollipops left with Carlos is y and that the number of friends he has is x

We know that he gave each friend 3 lollipops.
This means that:
number of lollipops he gave to his friends = 3x

To get the remaining lollipops with him, we will subtract the lollipops he gave to his friends from the total lollipops he had.
This means that:
lollipops left = original number - number of lollipops he gave to his friends
y = 83 - 3x

Hope this helps :)
