Final answer:
To find the number of grams of cashews in the second mix, calculate the amount of cashews in each mix separately. The second mix contains 14 grams of cashews.
Step-by-step explanation:
To find the number of grams of cashews in the second mix, we need to first calculate the amount of cashews in each mix separately.
In the first mix, Jonathan buys 400 grams of trail mix and it contains 18% cashew nuts. So, the amount of cashews in the first mix is 400 grams multiplied by 18%, which equals 72 grams.
In the second mix, Jonathan buys 200 grams of trail mix and it contains 7% cashew nuts. So, the amount of cashews in the second mix is 200 grams multiplied by 7%, which equals 14 grams.
Therefore, the second mix contains 14 grams of cashews.
