Answer:
If you're trynna simplify these are the answers:
4.) -116
5.) -13
Step-by-step explanation:
4.) −4((5)(4)+9)
=(−4)((5)(4)+9)
=(−4)((5)(4))+(−4)(9)
=−80−36
=−116
5.) 9+84−(6)(4)
=9+2−(6)(4)
=11−(6)(4)
=11-24
= -13

Population when at time 
We will substitute the value of time in above equation.

Answer:
I most likely think it is approximately 19%
Step-by-step explanation:
Assuming you mean still receive an allowance even though they dont do chores:
Ok In all the total number of students is 21. Out of those 21, 4 still receive an allowance even though they dont do chores. This is 4/21. Now all we have to do is convert 4/21 into a percentage. To do this we have to divide 100 by 21, then times 4 by that number:
100 / 21 = >> approximately 4.76
Now 4 times 4.76 :
4 * 4.76 = >>> approximately 19.04 % . We round it to 19%.
So the answer is 19%.
