Step-by-step explanation:
The ratio of people that can be served to milligrams of baking soda needed is:
Serving : Baking Soda
2 : 1600mg
Since you want 10 people, you can multiply this ratio by 5:5 to get
10 people served = 8000mg needed
8000mg = 8 grams
$9.99+ $3.99 + $1.52 = $15.50
10% =1/10 (just divide by 10)
$15.50 divided by 10 = $1.55
Steps :-
■ Eliminate the equations (subtract them). You'll get the value of 1 variable.
■ Then substitute in another equation to get the value of the other variable.
Answer :-
