Answer:
A) The cost is the same at 5 months.
Step-by-step explanation:
Lets use m to represent the number of months it will take for the cost to be the same. If we set up an equation, we can write:
75 + 10m = 50 + 15m
-50 on both sides
25 + 10m = 15m
-10m on both sides
25 = 5m
Divide by 5 on both sides.
5 = m
That means it will take 5 months for the costs to be the same.
Multiplying through by 8 we get
2x + 8 = 3x
8 = 3x - 2x
x = 8 (answer)

Answer:
18 days.
Step-by-step explanation:
We have been given that 12 painters paint the wall of a school in 21 days.
So the wall painted by one painter will paint the wall in
As one painter will paint the wall in 252 days, so to find the number of days it will take to paint the same wall by 14 painters, we will divide time taken by one painter (252) by 14.
Therefore, it will take 18 days to paint the same wall by 14 painters.
