The percent amounts of sand in 5 soil samples from the same garden are 73%, 68%, 88%, 74%, 81%. What is the average percent of sand in this garden?

Ok, so you add all of them together then divide by how many there are. So you do this. 73+.68+.88+.74+.81=3.84 then since there are 5 percentages then you do 3.84/5 =.768 so round it to the nearest tenth and your answer is 77%

0.73+0.68+0.88+0.74+0.81=3.84

3.84 divided by 5

=0.768x100

=76.8% or 77%
