Question

C = 12000 - ( 1500 . 2 + 1800 . 3 + 1800 . 2 : 3 )

Answer 1

12000 - (1500.2+ 1800.3+1800.2:3)

= 12000 - ( 3000 + 5400 + 1200 )

= 12000 - 9600

= 2400

Answer 2

12000 - (1500.2+ 1800.3+1800.2:3)

= 12000 - ( 3000 + 5400 + 1200 )

= 12000 - 9600

= 2400

Answer 3

C=12 000-(1 500.2+1 800.3+1 800.2:3)

C=12 000-(3 000+5 400+3 600:3)

C=12 000-(8 400+1 200)

C=12 000-9 600

C=2 400
