A packet of crisps contains 50g. if new size packets contain 15% more, how many grams of crisps are in the new size packets?

Question

can you work this out including workings out?

Answer 1

To find 15% of 50g take 50 x .15 (which is 15% as a decimal.) You get 7.5g.  So if the new pack is 15% more take 50g and add 7.5g to get your answer.
