I have a 73.3 and that is worth 70% of my mark. My final is worth 30%. What do i need to get on my final to finish with anything over a 70%?

  • Math -

    (70/100)(73.3 + (30/100)x = 70
    70(73.3) + 30x = 7000
    30x = 1869
    x = 62.3

    you will need 62.3% on your final

    check:
    .7(73.3) + .3(62.3) = 70
