How do i do this?? i am sooo confused. can someone please help me??

Question

Janet, Chrissy, and Jack want to divide their grocery bill evenly. They bouoght a apples for 90 cents each, b bananas for 60 cents each, and c cantelopes for $2.10 each. Write and simplify and expression representing the amount each person must pay.

Answer 1

First compute how much they paid for all that.

Total cost = 0.9 a + 0.6b + 2.1 c

Then divide the cost by 3.

The answer will be
C/3 = 0.3 a + 0.2 b + 0.7 c

You still need to know what a, b and c are to compute an actual number. That may be why you are confused.
