Uniform Rates, doing a job.
Think of the cats as the agents whose job is to consume cans of cat food.
RT=J to relate consumption rate, time, and quantity of cans of food.

Rate of cats consuming together is the sum of their rates,...

, or here more simply, .

(i):
8 cats, 7 days, want to know how many cans eaten.
, and you should already know from the description, . Evaluate j.

I did not answer question (ii). Carefully follow the uniform rates idea, and examine how question (i) was answered (or handled, even if not finished). In (i), you need to find the number of cans of food. j is used for the number of cans of food. (ii), you would already know r, the rate, so now for this question, you want to find the amount of time in days.
