It would be 7.54 because you fist have to put the numbers ordered smallest to biggest amount 7.15, 7.44, 7.48,7.60, 7.72, 7.73 so the numbers that are in the middle are 7.48 and 7.60 you add them up, and the result you divide by 2 which gives you 7.54.

17,16. That what comes next I think
Jenny's algebraic expression:
y = 33d
where y is the total number of posts
total tweets in 5 days
y = (33)(5)
y = 165 tweets
Antonio's expression:
y = 5d
total tweets in 5 days
y = (5)(5)
y = 25 tweets
Altogether they have posted:
165 + 25 tweets = 190 tweets in five days
