Final answer:
To find out how many grams each person ate, subtract the amount of cookies left behind from the total, and then divide by the number of people. In this case, each person ate approximately 192.6 grams of cookies.
Step-by-step explanation:
To find out how many grams each person ate, we need to subtract the amount of cookies left behind from the total number of cookies and then divide the result by the number of people.
So, the calculation formula is: (Total amount of cookies - Cookies left behind) / Number of people
In this case, the total amount of cookies is 990 grams, and each person leaves behind 27 grams. There are 5 friends in total. Plugging the values into the formula gives us: (990 - 27) / 5 = 192.6
Therefore, each person ate approximately 192.6 grams of cookies.
