Verified Answer :

First, you need to find how much an ounce costs. To do that, you have to divide 1.39 by 8. Then you get about 0.17. Now, you multiply 0.17 by 14, and get the answer of 2.38. Therefore, a 14-oz bottle of ketchup costs $2.38.

Cost for 8-oz bottle = $ 1.39
Cost for 1-oz bottle = 8/1.39
                               = 1.75 ( approx )

Cost for 14-oz bottle of ketchup = 14* cost of 1-oz bottle
                                                   = 14* 1.75
                                                   = $ 24.5

Cost for 14-oz of ketchup bottle is $ 24.5
