formula would multiply column B X $87.50, divide C by .5 and divide again by .8 for a total in column D. With this we could just create a calculator. So the problem would look like this I believe: (BX87.5)+(C/.5=?/.8)=e
Ideally this would be a hidden formula with just a box to insert hours, a box for parts cost and a result.
An agreed upon up front price is fine with me.
