Explanation:

A. 8 ounce for $ 1.44

`\text{Cost of 1 ounce pineapple = }(1.44)/(8)`

`\text{Cost of 1 ounce pineapple = }\$0.18`

B. 6 ounce for $ 1. 14

`\text{Cost of 1 ounce pineapple = }(1.14)/(6)`

`\text{Cost of 1 ounce pineapple = }\$0.19`

C. 18 ounce for $ 2.88

`\text{Cost of 1 ounce pineapple = }(2.88)/(18)`

`\text{Cost of 1 ounce pineapple = }\$0.16`

D. 10 ounce for $ 1.62

`\text{Cost of 1 ounce pineapple = }(1.62)/(10)`

`\text{Cost of 1 ounce pineapple = }\$0.162`
