Question

You usually buy the same small bottle of shampoo. There is a larger, 6.7-ounce bottle that says it gives you 25% more free. What is the size in ounces of the original smaller bottle of shampoo?

Answer 1

Answer:

The original smaller bottle of shampoo is 5.36 ounce

Step-by-step explanation:

Call the weight of the original smaller bottle = x

If the larger 6.7 ounce give us 25% more free

=> x + 0.25*x = 6.7

=> x * ( 1 + 0.25) = 6.7

=> x = 6.7 / 1.25

=> x = 5.36
