There are 18 packets.
Each packet has 10 cookies.
Let T = total number of cookies.
T = 10(18)
T = 180
There are 180 cookies.
Let C = cost of each cookie.
Use the equation C = 19.80/T.
You know what T is, right? Look above to see the value of T. Plug that T-value into the equation and solve for C.
After that, round your answer as instructed.
