What the bag says sounds like a lot of food for a cat that size to me. I ignore what it says on cat or dog food bags, as it always is too much in my opinion and animals, like us, are in better health generally if kept on the lean side. My cat weighs close to 10 pounds and he gets 1/3 cup of dry food a day plus 1/4 of a flat can of canned cat food and he's just right in weight and health.
I always judge what my animals should get by simply how they look and feel to me. If they gain weight I cut back and/or increase activity, and if they are thin or seem to be too hungry all the time I give them more. It doesn't have to be complicated at all.
