P(BA)=P(B)+P(A)-P(AnB)
= 0.51+0.8-0.468
=1.31-0.468
=0.842
P(BA) = 0.842
The number 144 is rational because it can be expressed by 144/1
For 30 hours Julio is paid 30r dollars.
For the extra 5 hours he worked he earns 5*1.4r = 7r dollars
So the equation is
30r + 7r = 436.60
37r = 436.60
r = 436.60 / 37 = 11.80
His normal hourly rate is $11.80 answer
