Question

Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? Tell Ella how much syrup she will have in each case.
20% syrup?

Answer 1

I'm guessing the % of syrup refers to the % of sugar it has, therefore:

20% = 20 / 100 = 0.2

0.2 * x = 0.5

x = 0.5/0.2

x = 2.5

She will have 2.5 lbs of syrup
