Betty has a tray of cookies and a tray of brownies.  She has a real sweet tooth and eats 3 cookies a day and 1 brownie a day.  If she starts with 60 cookies and 10 brownies, how many more cookies than brownies does she have after a week of eating like this? Let's think step by step and output the final answer after "####".

First we find how many cookies Betty will eat in a week by multiplying her daily amount by 7, meaning 7*3=<<21=21>>21 cookies eaten in a week.
We repeat this for the brownies, finding she eats 7*1=<<7*1=7>>7 brownies in a week.
We subtract the 21 cookies from the original amount of 60, finding 60-21= <<60-21=39>>39 cookies remaining.
We repeat this step for the brownies, finding 10-7= <<10-7=3>>3 brownies remaining.
In the end, therefore, Betty has 39-3= <<39-3=36>>36 more cookies than brownies.
