I'm pretty sure the answer is 65, if there is no value given for the "e" then it's most likely going to equal 1, and if it doesn't give any value then it equals 1 and the answer is 65e :)
15e and 10e are like terms, because they both have variables. 15e + 10e = 25e. So you would do 40 + 25e - which equals 65e
