    Nalia worked 3.5 hours more than Lisa. Together, they worked a total of 18 hours. Lisa worked h hours.

    A. h+3.5=18 B. h+7=18 C. h+(h-3.5)= 18 D. h+(h+3.5)=18

    So if Lisa worked h hours, we would say Lisa = h correct

    And we know in total the work hour is 18, so we have = 18 correct?

    Now notice it says Nalia worked 3.5 hours `more` than Lisa so what can we represent that with?

    It means we are using addition

    Good choices, so we have Natalia worked 3.5 more hours than lisa which we can represent as L = h+3.5

    No look at what I said, that should be N = h+3.5, so we have Lisa = h, total = 18 Our equation will be h+N=18 if we substitute N for h+3.5 we have h+(h+3.5)=18
