To make a smoothie, Moira added 320 grams of water to 80 grams of oatmeal, 100 grams of mango, and some protein powder. If the smoothie weighed 520 grams, how much protein powder did she add? (1 point)
• 3 grams
• 20 grams
• 200 grams
430 grams
To figure out how much protein powder Moira added, we need to subtract the weight of the other ingredients first.
The total weight of water, oatmeal, and mango is 320 grams + 80 grams + 100 grams = 500 grams.
Thus, the weight of the protein powder is 520 grams - 500 grams = 20 grams.
Therefore, Moira added 20 grams of protein powder.
