On Saturday, the fruit and juice bar was selling 21 glasses of fruit punch an hour. By 4 p.m., they had sold 126 glasses. If their goal was to sell more than 252 glasses of fruit punch, which inequality can be used to find h, the number of hours they must stay open to make their goal? A. 21h < 252 + 126 B. 126 + 21h > 252 C. 126 + 21h < 252 D. 126 + 252 > 21h

OpenStudy (anonymous):

it has to be more than 252 right

OpenStudy (anonymous):

I would say to eliminate C and A

OpenStudy (anonymous):

c or a

OpenStudy (anonymous):

th answer is either B or D, let me think for a sec

OpenStudy (anonymous):

B, because 21drinks per hour times 21 hours is 441, and 252+126 is less than 441

OpenStudy (anonymous):

441>378
