Dummy Question about breading pickup

I am having a brain fart and cannot recall how to manipulate equations to isolate a variable. Please don't tell my high school math teachers! I know the equation for figuring breading pickup is (breaded weight-unbreaded weight/breaded weight) x 100 = % pickup. I need to isolate for breaded weight. We have the raw weight and the % pickup. It was always my understanding that I should be able to do the raw weight and multiply by 1 + point "whatever the pickup is." For example,  90g raw weight and a 50% pickup to get the breaded weight you would have 90g x 1.50. Is this not correct? My co-worker is telling me that if there is a raw weight of 90g and a 50% pickup that I should just multiply the 90g by 2 to get 180g. These two methods produce different answers and I need to know which is correct or if we are both wrong, what is the proper way to calculate. I am sure I'm overthinking this but it's driving me crazy! Thanks for any help!

I agree with you. Your co-worker is wrong. Please let me know if I'm wrong.
