Donald bought a box of golf balls for $9.59. There were 18 golf balls in the box. About how much did each golf ball cost?

Answers

The price (9.59) divided by the number of golf balls (18).

9.59 (divided by) 18 = .53

One golf ball cost around $0.53 or 53 cents. 

You can also check the work by multiplying 18 by 0.53 which is 9.59.
One pack costs $9.59, which contains 18 balls. To obtain the cost of each ball, you divide $9.59 by 18, which is about 53 cents
