A (Elise needs 7 quarts of ice cream)
Step-by-step explanation:
Okay so we know that Elise is serving 42 people, since she's making 42 chocolate ice cream sundaes.
Since it takes 3 quarts to serve 18 people, we know that the amount of people divided by 6 will equal the quarts.
So 42 people divided by 6 equals 7 quarts.

Let x=grams of 70% alloy:
0.70x+16×0.20=0.30(x+16)
0.70x=0.30x+4.8-3.2
0.40x=1.6
x=1.6/0.4=16/4=4g
4 grams of 70% alloy are needed.
