Introduction to Writing and Solving Linear Equations in One Variable - Item 2737

Questionz
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

Answer 1

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

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.
