Question 3:
If Factory produces 1.500 light bulbs in one minute, how many light bulbs will it produce in t seconds?
A) 1,500t
B) 25t
C) 25/t
D) 750/t
C) 90,000/t
My Question how you solve that if you pick numbers like T=60 to solve t seconds?
Question 5:
A group of 10 people decides to share equally in an apartment that costs r dollars to rent each month. If X people drop out of the group, how much more, in dollars, must each remaining person pay?
A) rx/ 10(10-x)
B) 10r/x
C) r/10(10-x)
D) r/10-x
E) rx/10-x
My questions is when picking number if choose to pick r= 100 and x=4 it does not work why, but if choose r=100 and x=5 to solve it works perfectly and the answers is A. Can you explain in detail why?
For example 10-5= 5 people are left. So, 100/10 = 10 and 1005= 20. Then 20 - 10 = 10. Then I check which answer chooses work A is the answer. but don't know when R=100 and X= 6 it does not work?
