So u will do 88+84=172+88=260+91=351 and that is all four tests added up now u have to divide the answer by 4 because it was four tests averages 351/4=87.75 wich is aproxamately 88 so with all four of them added wich is 351 u will add the answer choices so 351+96=447/5=89.4 wich is aproxamately 89 351+97=448/5=89.6 wich is aproxamately 90 351+98=449/5=89.8 wich is aproxamately 90 351+99=450/5=90 so i would say that 99 points is the one she needs to score because it isnt asking for aproxamately so it is 99 points
