11. a club is selling tubes of cookie dough for a fundraiser. if the goal is to raise at least $300, how many tubs of cookie dough must they sell at $5.50 each to meet that goal? write and solve an inequality.
the answer is x>55 tubs. Im not sure how to get that answer

Answer 1

10. 120>(or equal to)5h
the reason why you have to multiply 5 by h is b/c you make $5 an hour and h represents hours...
11. 300>(or equal to)5.5x
you solve this by dividing each side by 5.5... 300/5.5 is about 55 tubes so then it becomes: x>(or equal to)55 tubes
