Answer: x= 0.20(5.4) or x=0.20 (5.4 ounces).
Explanation:
Given : You usually buy a 5.4 ounce bottle of lotion.
There is a new bottle that says it gives you 20% more free.
i.e. Size of new bottle = 20% of 5.4 ounces
= 0.20 (5.4 ounces) [we divide percentage by 100 to convert it into decimal]
Also, the size of the larger bottle is given to be x.
i.e. x=0.20 (5.4 ounces)
On solving , we get
x= 1.08 ounces
Hence, required equation is x= 0.20(5.4) or x=0.20 (5.4 ounces).
