Is it correct to word "10% * 50 + 50" as "10% upper 50"?

    I read that as 10% times 50 plus 50

    Is there any other statement in mathematics for this with the "upper" definition?

    Replace "50" with "x"
    x + 10% x

    Upper meaning upper bound? Upper percentile? Upper quartile?

    I need a bit more background on what lesson or concept you are working on right now.

    Yes, it's close to the upper bound. I just wonder what we interpret the below inequality is?
    y > 10% x + x

    My two cents: y is greater than 10% upper x

    What do you say?

    If we factor your expression, we get:
    y > x(10% + 1)
    y> 1.1x Since 10% is 0.1

    I read it as y > 110% of x

    Yes, that's a way. However, in my case, I need to interpret the expression with the "upper" definition. Could you help me?

    Yes, then if we are dealing with percentiles, I read that as 10% upper x%

    Thank you! But is it correct if we read % after x? I thought it should be "10% upper x". Please confirm.
