Hello, can anybody please explain this question to me and show me how to work it out please.
Q1. Florence recorded her test results in the back of her exercise book.
She says. 'My mean mark in these five tests was 78%'
Unfortunately, Florence noticed that there was an ink blot covering her mark in art. Can you help her to work out her mark for art?
Thanks for you help kalagota but i still don't know what mark florence got in art
