The mistake is in step 2. You cannot combine two terms into one; 2(-20) + 3(-25) doesn’t equal (3 + 2)(-20 + -25) Evaluate each term separately: (-40) + (-75) = -115 The way it was combined would be: 5 x (-45) = -225. A difference of -225 - (-115) = -110 The same applies to the last 2 terms. You have to evaluate each term separately. (-40) + (-75) + (100) + (200) = 300 - 115 = 185 Thus 185 is the correct answer. Hope this helps :)
