Answer:

Step-by-step explanation:
Joint variation problem solve using the equation y = kxz.
e ∝ fg
e=kfg
now substitute the values

The relationship will be:

Each person will get a full brownie leaving you left over with 2 full brownies. You can cut both of the remaining brownies into 3rds giving you 6 pieces. Each person can then get 2 prices. This is 1 and 2/3 brownies per person
80, divide 200 by 2.5 and you get 80. Check by multiplying 2.5 and 80, which equals 200
