Answer:1680grams
Step-by-step explanation: You can do it in two ways. First, you may calculate how many grams Brenda needs for 1 person and that's 480grams divided by 4 and that's 120grams. Then you can easily calculate 14 people as = 14 × 1person and since 1 person is 120g, then 14people= 14 × 120g = 1680g.
In another way, you can place the number of people in a ratio and equate it to the ratio of the grams. This is using a system of equivalent fractions. So you put 4 people divided by 14 people equal to 480 people divided by x grams. You have: 4/14 = 480/x. Cross multiply and you can have your answer as 1680grams. I hope that was helpful dear. Happy new year in advance.
