Sin x is possitive in two quadrants :
quadrant I and quadrant II
in quadrant I, cos x is positive
in quadrant II , cos x is negative
so i think the answer is : quadrant II
hope this helps
<u>First what I did was take out the 5 dollars. So I did 25 minus 5. </u>
25 - 5 = 20
<u>Next, I divide the left over 20 dollars by 1.25 to see how many tokens Marco could buy. </u>
20 / 1.25 = 16
<u>Which i came up with 16. So Marco can buy 16 tokens and still have enough money to use to buy lunch. </u>

<u>HOPE THIS HELPS! :)</u>
