David signed up to provide snacks for his daughter and her school group's camping trip. He found a package of granola bars in bulk for $60 that he thought would be enough for everyone for a few days. He also wanted to buy some boxes of fruit snacks, which were $4 each. He just needed to decide how many to buy, and then figure the total cost.
Which equation represents the cost (C) of David's snack donation, where F is the number of boxes of fruit snacks he buys?
- 3c+60=F
- 4F=60+c
- 4c=60+F
- 4F+60=C
