Approximately #10# cents per ounce

Explanation:

To calculate the unit price (how much #1# ounce costs), divide the cost of #28# ounces by #28#.

#2.89/28=0.10321428571#

#2.89~~0.10#

To use an equation with #c# representing the unit price:

#28c=2.89 rarr 28# times the unit price equals #$2.89#.

#c=0.10321428571#
