Answer:
they are both equal 12x+8 is equal to 12x+24
Step-by-step explanation:
distribute:
3 x 4x = 12x 3 x 4 = 24
No, a & b are not independent if they're mutually exclusive.
Mutually exclusive means the two events cannot occur simultaneously. So if "a" happens "b" cannot. In contrast, two events are independent if the occurrence of one has no effect on the occurrence of the other.
In this situation the revenue is the total sales you make before all expenses.
To find the profit: 3000 - 1500 - 500 = 1000.
Your profit is $1,000.
