4

Step-by-step explanation: PEMDAS

Parenthesis first: (Left to right)

24 ÷ [ ( 16 ÷ 2 ) - ( 4 ÷ 2 ) ]

24 ÷ [ ( 8 ) - ( 4 ÷ 2 ) ]

People think "no exponents or multiplication, so division!" But, no. The brackets are also considered parenthesis. So you have to to 8 - 2 first.

24 ÷ [ ( 8 ) - ( 2 ) ]

24 ÷ [ ( 6 ) ]

At this point, you can get rid of the parenthesis and brackets because there is only one number in it.

24 ÷ 6

= 4

they would have to work 32 hours.
