$6.99 for 90 fl. oz of detergent is a better buy.

Arithmetic operations is a concept that concerns the study of mathematical operations like addition, subtraction, division, and multiplication.

The determination on the type which is a better buy can be estimated by finding the cost of each detergent in the two cases.

For the first case, we are being told that It cost $3.99 for 25 fl. oz. of detergent.

From that, the price for 1 fl. oz will be:

[tex]\mathbf{x = \dfrac{3.99 \times 1 }{25}}[/tex]

x = $0.1596

For the second case, if the price for 90 fl. oz is $6.99

For 1 fl.oz, we have:

[tex]\mathbf{x = \dfrac{6.99 \times 1 }{90}}[/tex]

x = $0.0777

Therefore, we can conclude that $6.99 for 90 fl. oz of detergent is a better buy since the amount of each detergent is lesser than that of 25 fl. oz.
