Question

Jun used x milliliters, or 90%, percent, of his favorite bottle of hot sauce. Which of the following expressions could represent the volume of a full bottle of Jun's favorite hot sauce, in milliliters?

Answer 1

E) x/0.9

Explanation:

90% = 90/100 = 0.9

To find 90% of the full bottle, we would multiply the amount in the bottle by 0.9. This would be 0.9x.

However, we are trying to find the amount of the full bottle. Instead of multiplying, we divide. This makes it x/0.9.

Answer 2

Option D.
`(10)/(9)x\ ml`

Explanation:

Let

v------> the volume of a full bottle of Jun's favorite hot sauce, in milliliters

we know that

Using proportion

`(x)/(90)(ml)/(\%)=(v)/(100)(ml)/(\%)\\ \\v=(100)/(90)x\\ \\v=(10)/(9)x\ ml`
