Question

You usually buy a 5.45.4 ounce bottle of lotion. There is a new bottle that says it gives you 20%20% more free.

Answer 1

Answer: The required equation is,

$x = \frac{120\times 5.4}{100}$

Step-by-step explanation:

Let x be the size of the larger bottle,

Since, the size of smaller bottle of lotion = 5.4 ounces,

According to the question,

The larger bottle gives 20% more free lotion,

The size of the larger bottle = The size of smaller bottle of lotion  + 20 % of the size of smaller bottle of lotion

= 120 % of the size of smaller bottle of lotion

= 120 % of 5.4

$=\frac{120\times 5.4}{100}$

$\implies x = \frac{120\times 5.4}{100}$

Which is the required equation that could be used to find the size of the larger bottle.

Answer 2

Answer:

Th required equation is $x=5.4+\frac{20}{100}\times (5.4)$.

The size of the larger bottle us 6.48 ounce.

Step-by-step explanation:

The size of original bottle of lotion = 5.4 ounce

It is given that a new bottle gives you 20% more free.

Let x be the size of new bottle.

Size of new bottle = Size of original bottle + 20% of Size of original bottle

$x=5.4+\frac{20}{100}\times (5.4)$

$x=5.4+0.2\times (5.4)$

$x=5.4+1.08$

$x=6.48$

Therefore, the size of the larger bottle us 6.48 ounce.
