81 cookies left
77 orange trees

if you get rid of 7 sugar cookies, that gives you 21 sugar cookies and 60 chocolate chip cookies, which is 81 cookies left
The second one there are 15 rows of 7tree  which is 105 total trees
if the last 4 rows are cherry that makes 7*4= 28 cherry trees
that leaves you 11 rows left with orange trees which is 11*7=77orange trees
