Laundry detergent comes in 2 sizes. Box A is $7.62 for 2.5 Litres, Box B is $5.74 for 1.5 Litres. Which is the better deal and by how much?

$7.25 = 2.5, so divide by 7.25 by 5 = 1.45 <- better deal & $0.46333333333 per litre.

5.74 = 1.5, so divide 5.74 by 3 = 1.91333333333

Step-by-step explanation:

Why 3 and 5 - 0.5 is 5 times 2.5 and so is 0.5 times 3= 1.5

1.91333333333 - 1.45 = $0.46333333333 per litre.
