Answer 2

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,

`\Rightarrow0.5\text{ lbs }- 1.5\%`

`\Rightarrow x+0.5\text{ lbs }- 100\%`

On writing the proportion,

`\Rightarrow(0.5)/(x+0.5)=(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=(49.25)/(1.5)\approx 32.833\ lbs`

To get 1.5% syrup Ella should add 32.833 lbs of water. The total weight of syrup is 33.333 lbs.
