Estimate: 40+20 = 60 Actual: 38+23 = 61
38? I know i was supposed to answer that but it really wasn't a question.
61
It is: 23+(23*38) = 897
according to a study done by an electronics waste facility in washington, over 38 million is the estimation...
100*23/38 = 60.526% (to 3 dp)
38
38 is 23% of 165.2
23
One possible answer... (38 - 28) + (38 / (23+15)) + 28 = 39
10:23 am 60 - 45 = 15 38 - 15 = 23
38 + 15 = 53 38 - 15 = 23
