To answer this, you will replace the variable m with the given values to see which one is a true statement.
4 x 1 + 8 = 36
12 does not equal 36
4 x 7 + 8 = 36
36 = 36; this one is true.
The correct value is 7.
Answer:
The time taken by the four workers to paint the room is 1.5 hours.
Step-by-step explanation:
3 workers can paint a room in 2 hours
So, 1 worker can paint the same room in 6 hours.
Now the number of workers is 4.
So, the time in which the 4 workers can paint the same room is
= 6/4 = 1.5 hours
It's the same because you're trying to find net price (end price)
You're going to take in both scenarios 100%-15%= 85%
You're always going to be paying only 85% of the price.
