What is original value if the total is 40 and the sale tax is 8.75%?
y * 8.75 = 40 is this the setup to solve the problem?

y(1+.0875)=40
solve for y, the original value. 
Thank you for helping bobpursley
I forget to put 1 for (1 + .0875).
Here is what I solve this:
y(1+.0875)=40
1.0875y=40
y=40/1.0875
y=$36.78
Thanks
