Mean is the average. You would add up all the numbers and divide by how many numbers you have. 433/10=43.3
4.5 and 3.5 it is the same but 4 and 3 are different you get it ?
We are given that each bag of trail mix consumes 2.3 oz of nuts. To know the amount of bags of trail mixes that can be made using 27.6 oz of nuts, all we have to do is cross multiplication as follows:
2.3 oz of nuts ............> 1 bag of trail mix
27.6 oz of nuts ...........> ?? bag of trail mix
number of bags = (27.6*1) / 2.3 = 12 bags
$ 7 dollar reduction....that means new price is (32 - 7) = 25
percent decrease = (original number - new number) / original number..* 100
(32 - 25) / 25....* 100
7/25 * 100
0.28 * 100
28% decrease <==
