Plugging this into a calculator: (2000/2)4.5 + (3000/2000)40 + (18 * 3000) = 58560.
OR you could do...
2000/2 = 1000
1000*4.5 = 4500
3000/2000 = 1.5
40*1.5 =60
3000 = 3*1000
18*3 = 54
54*1000= 54000
adding them all together
4500 + 60+ 54000 gives 58560
Which is the same as HELPMEEEEEEEE....EEE's answer!
