im thinking d

dan815 · Answer

cuz if u set the lowest ammnt 6800, thats not even 99% of the first store and its like more than 99 percent of the 2nd store

dan815 · Answer

and u need 99% of both stores so 6800 doesnt work

dan815 · Answer

it is D 100% sure now

dan815 · Answer

basically by that reasoning you cannot select a monthly sales price for 1 store and expect that to equal to the 99% sale price for the 2nd store unless both of their graphs are inequal but in these case the 2 peaks are different ergo not equal so not possible to select 1 price that wud at the same time give you 99% sales for both
