Given the statement:
You buy 8 packs of markers with 20 markers in each pack
You already had 10 markers.
Calculate the total number of markers that you have.
Solution:
It is stated in the given that each pack of markers contain 20 markers, and since you've bought 8 packs, we can multiply 8 by 20 in order to find how many markers there are in total.
= (8)(20)
= 160
add 10 to 160 since you've already had 10 markers with you.
= 160 + 10
= 170
Final answer:
You have a total of 170 markers.
