    Percentages.

    A question came up on a mock exam paper and i'm not sure if i've got the right answer or gone wrong somewhere. Please could you check them for me!

    1. Keith, who was on a salary of 34 200, was given a pay rise of 4%. What was his new salary?
    34 200 x 1.04 = 355.65

    2. Increase 80 by 5 %.
    5/100 x 8000 = 400. 4 + 80 = 84

    Thanks in advance

    Oh Molly, you're so good at making tiny errors!

    For the first part, you've done the correct calculation, and received an incorrect answer. 34200 x 1.04 = 35568, not 355.65!

    The rest is fine.
