At the store you have 2 options for Speedy Clean Laundry Detergent. One bottle costs $4.99 for 50 fl . oz The other bottle costs $7.50 for 90 fl. oz Which is the better buy?​

the bigger bottle (90 fl. oz) is better value

Step-by-step explanation:

One method is to scale the quantities up to the same value.

The LCM (lowest common multiple) of 50 and 90 is 450

9 of the smaller bottle will cost $44.95 and contain 450 fl. oz

5 of the bigger bottle will cost $37.50 and also contain 450 fl. oz

A second method is to find the cost per (say) 10 fl. oz from each bottle

In the 50 fl. oz bottle each 10 fl. oz costs 4.99 / 5 = $0.998

In the 90 fl. oz bottle each 10 fl. oz costs 7.50 / 9 = $0.8333...

(x^2-9)/ (x + 3) = x-3
