Question

It cost $3.99 for 25 fl. oz. of detergent or $6.99 for 90 fl. oz. Which is a better buy?

Answer 1

$6.99 for 90fl because 3.99 plus 3.99 is about 8 and 25 plus 25 is 50fl which is less the 6.99 for 90fl

Answer 2

The 90 fl. oz. of detergent for $6.99 is a better deal because ;$3.99 per 25 fl. oz. or, 3.99/25, is equal to $0.16,and$6.99 per 90 fl. oz. or, 6.99/90, is equal to $0.08 (rounded).Thus, the 90 fl. oz. bottle costs less per ounce of detergent.
