your question:
please answer and show all of your work.
answer:
well if they cost 1.50 each it would be 1.50x then your friend bought 2 ($3.00) then the total is 10.50
sooo
1.50x + 3.00= 10.50
we then solve it
1.50x + 3.00= 10.50
-3.00 -3.00
1.50x = 7.50
------- ------
1.50 1.50
x= 5
you bought 5 magazines
hope this helps, have a good night :)
