Okie, there is no follow up question so I assume that you wanna find out the range in which Serena needs to score in order to make the b team. So it is basically just 8 points under and 8 points over. 92 - 8 = 84 lower limit 92 + 8 = 100 upper limit So to make the b team, she needs to score somewhere between or equal to 84 and 100. I hope this helps :-)
