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 $270. That would be 24 hours.
If he worked 4-hour days, that'd be %50/day, and he'd only have to work 5 days, or 20 hours.
Jordan decides to start a garden care service. He charges 20$ 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.

Ok so whats the inequality to get 20 hours as my answer?
Thanks
Thanks
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?
