mom made 68 chocolate chip cookies 36 oatmeal cookies and 24 sugar cookies my friend and i ate 19 cookies how many cookies are left

To find out how many cookies are left, we need to subtract the number of cookies you and your friend ate from the total number of cookies that your mom made.

Total number of cookies = 68 (chocolate chip) + 36 (oatmeal) + 24 (sugar) = 128 cookies

Number of cookies left = Total number of cookies - Number of cookies eaten
= 128 cookies - 19 cookies
= 109 cookies

So, there are 109 cookies left.
