It’s definitely-20
Add 9 to both sides to cancel it out so it is now
4x-20=5x

It would include 25 gifts for the cost the same amount either way
<em><u>Solution:</u></em>
Let "a" be the number of gifts to be wrapped
He can get them wrapped at the department store, which charges $2 per gift
Therefore,
Cost at department store: 2(number of gifts)
Cost at department store: 2a
The customer can pay his niece a flat fee of $50 to wrap all of his gifts
Cost at his niece: 50
He has a certain number of small packages, it would cost the same amount either way
Therefore,
Cost at department store = Cost at his niece
2a = 50
Divide both sides by 2
a = 25
Thus it would include 25 gifts for the cost the same amount either way
350 + 275 + 35 + movies and popcorn= 710
660 + movie and popcorn = 710
Movies and popcorn = 710 - 660 = 50
$50
