Question

You buy 8 packs of markers with 20markers in each pack. You already had 10 markers. Which equation shows how to calculate the total number of markers, m, you have?

Answer 1

`m=10+8\cdot{x}`

`=20\cdot{8}=160`

The amount of markers that you buy is 160. The x is the equation should be the number of markers in the pack. The equation is:

`m=10+8\cdot{x}`
