A snowstorm lasted for three days. Durning the storm, 8 inches of snow fell on the first day, 6 inches of snow fell on the second days, and 9 inches of snow fell on the third day. Altogether, how many feet of snow fell during the three-day snowstorm?

Basically we need to add all of the inches

Step-by-step explanation:

so...

8 inch ( first day ) + 6 inch ( second day) + 9 inch ( third day )

add all those inches together what do you get?

23 inches in total. So altogether 23 inches of snow fell during the 3-day storm

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
