Answer 1

Nguyen can make 12 gallons of lemonade with 18 gallons of lemonade concentrate.

Explanation:

Given,

4.5 gallon of liquid lemonade concentrate is used in 3 gallons of water to make lemonade.

We have to find the amount of water used to make lemonade with 18 gallon lemonade concentrate.

Solution,

Since,

To find the amount of water we use the unitary method.

4.5 gallon of liquid lemonade concentrate is used in 3 gallons of water to make lemonade.

So, for 1 gallon of liquid lemonade concentrate amount of water =
`(3)/(4.5)`

So, for 18 gallon of liquid lemonade concentrate amount of water =
`(3)/(4.5)*18=(54)/(4.5)=12\ gallons`

Hence Nguyen can make 12 gallons of lemonade with 18 gallons of lemonade concentrate.
