There are four tests in a year. The first test is worth 26%, the second is worth 20%, the third test is worth 30%, and the fourth test is 20%. Maria received a 59% on her first test. To receive a final mark of 65%, what is the minimum she needs to obtain on each test?

Can someone please explain to me how I would do this? Thank you!
