  1. Suppose she works c hours at the cafe, and m hours at the market.

    To earn at least $800, we need
    10c + 8m >= 800

    60 hours at the market means $480
    at most 90 hours per month means at most 30 hours at the cafe, for $300

    If you have trouble with the graphs, google graphing inequalities for examples. Or, heck, study your text...
