Abusiness had a goal of selling 500 bags of chips. with 3 days left they have 322 to go. at least how many do they need to average per day to meet their goal

To get the average, you must divide your number (322) by how many terms you need (3 days).
322 ÷ 3 = 107.333333333
Because they can't sell a third of a bag of chips we must round that up due to the logic of the question getting:
108 bags of chips a day

The price decreased by 40 percent㏒㏒㏒㏒㏒㏒㏒㏒㏒㏒㏒㏒㏒∞㏒∞㏑⊕⊆⊂ф
