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?
Round your answer to the nearest tenth.

Answer 1

If the larger bottle of shampoo gives 25% more for the same price, then it must contain 1.25 times the amount of shampoo in the smaller bottle. Let's represent the size of the smaller bottle as x ounces.

Thus, we can set up the following equation:

x * 1.25 = 6.7

Solving for x, we get:

x = 6.7 / 1.25

x ≈ 5.36

Therefore, the size of the original smaller bottle of shampoo is approximately 5.4 ounces (rounded to the nearest tenth).
