Final Number for Project isn't Right

Screenshot 2022-03-09 174533

I basically imported this formula in appinventor and put 3 different textboxes for the 3 values, but the answer is wrong compared to my physical work

i believe the error is either a Order of Operations Problem or a string-integer problem

heres the formula in appinventor by the way

Order of operation looks OK.

Show your textbox values. AI2 will in general convert strings to numbers, but there are some exceptions


The answer is `"90%"

and see here (Example #1)
