Answer:
9 grams
Step-by-step explanation:
<u>We can use these equations</u>:
y = ax
- Where y is the total amount of baking soda (in mg)
- Where a is the number of servings
- Where x is the amount of baking soda in one single serving (in mg)
Here we know that y = 1800 and a = 2, so we will need to solve for x
- Solving for x we get
and plugging in our known values we get
and this simplifies to 900
- This means one serving contains 900 mg of baking soda
We can now change the equation to solve for the total amount of baking soda required to serve 10 people
- We know that a = 10 and x = 900
- The equation is already solved for y, so plugging in our new values we have y = (10)(900) = 9000 mg
- The recipe will require 9000 mg in order to serve 10 people
Now there are 1000 mg in 1 g, so converting mg to g we have 9000 mg is equivalent to 9 grams
