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