Ella has to add 32.833 lbs of water to get 33.333 lbs of syrup.
Solution:
Ella has 0.5 lbs of sugar. Let x lbs be the amount of water Ella should add to get the 1.5% of syrup,
[tex]\Rightarrow0.5\text{ lbs }- 1.5\%[/tex]
[tex]\Rightarrow x+0.5\text{ lbs }- 100\%[/tex]
On writing the proportion,
[tex]\Rightarrow\dfrac{0.5}{x+0.5}=\dfrac{1.5}{100}\\ \\\Rightarrow0.5\cdot 100=(x+0.5)\cdot 1.5\\ \\\Rightarrow50=1.5x+0.75\\ \\\Rightarrow1.5x=50-0.75\\ \\\Rightarrow1.5x=49.25\\ \\\Rightarrow x=\dfrac{49.25}{1.5}\approx 32.833\ lbs[/tex]
To get 1.5% syrup Ella should add 32.833 lbs of water. The total weight of syrup is 33.333 lbs.
