Jordan decides to start a garden care service. He charges 20$ for the first hour and 10$ for each additional hour. He works 5 days a week and takes care of one different garden each day. How many hours will he need to work to earn at least 250$.

Write and solve an inequality for the total number of hours jordan needs to work.

  1. 20+10x >= 250
    but that's only if he works all in one stretch.

    Since he works day by day (presumably for 8 hours per day, but you don't say), each day he gets

    20 + 7*10 = $90
    So, to make $250, he needs to work 3 days, making $270. That would be 24 hours.

    If he worked 4-hour days, that'd be %50/day, and he'd only have to work 5 days, or 20 hours.

  3. why do you want 20 as the answer? In any case, think about it. He makes $50 for a 4-hour day. So, if he works d days, what do you need?
