Question

To make a smoothie, Moira added 320 grams of water to 80 grams of oatmeal 100 grams of mango and some protein powder. If a smoothie weighted 520 grams how much protein powder did she add?


430 grams
200 grams
3 grams
20 grams

Answer 1

To find out how much protein powder Moira added to her smoothie, we can start by adding together the weights of the other ingredients.

The ingredients she added are:
- Water: 320 grams
- Oatmeal: 80 grams
- Mango: 100 grams

Now, we add these weights together:

\[
320 \, \text{grams} + 80 \, \text{grams} + 100 \, \text{grams} = 500 \, \text{grams}
\]

The total weight of the smoothie is given as 520 grams.

Now we can find the weight of the protein powder by subtracting the total weight of the other ingredients from the total weight of the smoothie:

\[
520 \, \text{grams} - 500 \, \text{grams} = 20 \, \text{grams}
\]

Thus, Moira added **20 grams** of protein powder.
