you buy 8 packs of markers with 20 markers in each pack, you already had 10
markers, which equation shows how to calculate the total number of markers, m, you
have?
clear
check
m = 20. 8 - 10
m = 10.8 + 25
m = 8.20 + 10
m = 8 + 10

m = 8.20 + 10 is the equation that shows the total number of markers.

Step-by-step explanation:

Number of packets of markers purchased  = 8

Number of markers in each packet = 20

⇒Total numbers of markers purchased =  Total packets x Markers in each              

                                                                                                           pack

= 20 x 8

Number of markers already there = 10

⇒ The TOTAL NUMBER OF MARKERS (m)

= Number of markers purchased + Number of markers already at home

or, total markers  m =  (20 x 8)  +  10

Hence, m = 8.20 + 10 is the equation that shows he total number of markers.
