A. If she needs 5 tomatoes for a family of seven, then we need to find how many tomatoes it takes to feed only one person and then multiply that by 100z
5/7 = 0.714… tomatoes per person
Multiply this by one hundred
0.714 * 100 = 71.43 tomatoes.
Check:
5/7 = ?/100
Solve for ?
? = 71.43 tomatoes, but you technically can’t bring 0.43 tomatoes, so round that to 72 tomatoes
B. We would need to solve for
5/7 = 58/?
? = 81.2 people, but you should round down here because there isn’t enough chili for that 82 person, and there are not 20% of a person walking around looking for some chili.
