Answer:
35 people in each
Step-by-step explanation:
105÷3=35
When you do the inverse operation which in this case would be subtraction you do 54-17 and then you do 17 minus 17 which leaves you with the variable 54-17=34 so k=34
In the order of operation, multiplying or dividing don't take preference over the other. So with them, you work from left to right.
This means for this question, you first divide, then multiply.
$0.00995 is the correct answer.
$3.98/400=0.00995
