Jamie is organising the food and drink for an annual conference.
Jamie needs to work out much coffee is needed for 800 people.
He assumes 68% of the people will drink coffee.
10.6g of coffee is needed for each cup of coffee.
Jamie assumes that each person who drinks coffee will drink 2 cups of coffee.
Using his assumptions, work out the amount of coffee Jamie needs to the nearest gram.
Answer:
Since everyone is drinking 2 cups of coffee then you need to multiply 10.6 by 2 to find the total grams of coffee at 21.2g
Then find 68% of 800 by doing 0.68 x 800 which is 544 people drinking coffee.
Then multiply them together so 544 x 21.2 = 11532.8 or 11533g
