Ms Nina has 10lb of 25% sugar syrup. How much does she need to add to make 10% sugar syrup

Answer 1

Let x be the amount of sugar syrup that Ms. Nina needs to add.

First, let's write the equation for the sugar content in the final mixture:

0.25(10) + 0(x) = 0.10(10 + x)

2.5 + 0 = 1 + 0.1x

Simplifying:

0.1x = 1.5

x = 15

Ms. Nina needs to add 15lb of sugar syrup to make a 10% sugar syrup.
