Can someone walk me through the steps in solving this question

So, we know that, in 1oz of baked potato, there are 48.3 calories, ok..how many calories in 3 and 1/3 oz then?

now, bear in mind, we first convert the mixed fraction to "improper", and then use that,





now, we know that in 1oz of chicken gas 24.6 calories, so, how many calories then in 5 and 1/4 oz?

 



so, how many calories in that meal?  well, p + c.
