1) in one minute for first wiil be 1/20
the other 1/30, it means that A paint in one minute 1/20 and B 1/30 then A+B in one minute 1/20 + 1/30 = 3+2/60 = 5 / 60, 5/60 = 1/12
if in one min they make 1/12 then in 12 min they paint all the wall
There are two ways to do this:
Way 1- Since you know there are 4 people and each will pay 25%, you know that every person will pay equally / the same amount so you can just do 115/4 and get $28.75 per person
Way 2- You can convert 25% into a decimal by multiplying it by 100 and getting 0.25 and multiplying 0.25 x 115 to get 25% of 115, which is what everyone will pay and you get B $28.75

The temperature 6 hours after day break is 53 degrees
Step-by-step explanation:
The temperature was 65 degrees at daybreak. Then it dropped two degrees per hour until dusk. This decrease in temperature can be modeled by the equation,
y = -2x + 65
according to this equation
y= temperature after day break
x= no of hours ( in this case 6)
So equation becomes
y= -2 (6) +65
y= 65- 12
y= 53 degrees
So the temperature 6 hours after day break is 53 degrees
