What do I do for this

its 7 or B.

Step-by-step explanation:

7 is the number being repeated the most (dunno if that makes sense so the mode is the most common number in a data set.)

5.00+5.5+5.10+5.15+5.20+5.25= x

x is whatever the cost is.

if you want x, it is 31.2

or

y=5.00+5.5+5.10+5.15+5.20+5.25

If you want the equation in linear form (as in y= _x+b), then it is:

y=0.001x

sorry if im wrong! :D

Step-by-step explanation:

Just ask!

Hope this helps... :)
