150, I believe
"if 40% of a number is 60" (40/100) * x = 60 (.4) x = 60 [reduce or just write it this way] x = 60(.4) [multiply both sides by .40]
1 % of 330 is 3.3 and 3.3x8=26.4 so 26.4+330=356.4
356.4
The last one will give the incorrect slope
To find a fraction equivalent to 3/5 multiply both top and bottom numbers by the same number .Example of answer 6/10.
