A magician performing at children's birthday parties charges $120.00
total for a one-hour performance with ten goodie bags for children at
the party. She will provide additional goodie bags for $2.50 each. For an
additional $25.00, she will also present a 15-minute laser light show.
The magician is always paid on the day of the show, receives no tips or
other additional payments, and never varies the length of the show. If
the magician performs exactly four shows one weekend, presents the
light show at three of those performances, and collects $635.00 total,
how many additional goodie bags did she provide?
