Question

Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need to make 1.5% syrup?

Answer 1

He needs 0.075 lbs of sugar and 4.925 lbs of water.

Explanation:

Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.

Note

5 lbs - 100%

x lbs - 1.5%

Write a proportion:

`(5)/(x)=(100)/(1.5)`

Cross multiply:

`100x=5\cdot 1.5\\ \\100x=7.5\\ \\x=(7.5)/(100)=0.075`

So, he needs 0.075 lbs of sugar and 5 - 0.075 = 4.925 lbs of water.
