First: 5/20
second: 6/19
5/20 x 6/19 = 30/380 = 15/190 = 3/38. The answer is B
So what you want to do is multiply 245 by 1.65 (because it’s +65%) and by doing that you get $404.25 :)
I think im not completely sure but it might be -3
In other words:
4 x sq rt symbol(625)
4 x 25 (25 is square root of 625)
4 x 25 = 100
Your final answer is 100.
