Answer:
He made 40 grams of 20% sugar syrup.
Step-by-step explanation:
Alan threw 8 grams of sugar into 32 grams of water and got 8 + 32 = 40 grams of sugar syrup.
To determine the percent of sugar, note that
40 g - 100%,
8 g - x%,
then
[tex]\dfrac{40}{8}=\dfrac{100}{x},\\\\40x=8\cdot 100,\\ \\40x=800,\\ \\x=20\%.[/tex]
