Answer: Number of hours they all will take is
Step-by-step explanation:
Since we have given that
Number of hours Walter and Bill takes to do the job = 4 hours
Number of hours Tom alone takes to do the job = 3 hours
We need to find the number of hours takes them together to decorate the room.
Work done by Walter and Bill =
Work done by Tome =
total work done by three is given by
Hence, Number of hours they all will take is
Ok so
so firs what we do is
1150/12 and ignor remainder
95 and remainder is 10
therfor we have 95 trucks full and 10 cars in the last truck
A = P(1 + rt)
A = Total Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
r = Rate of Interest per year in decimal; r = R/100
R = Rate of Interest per year as a percent; R = r * 100
t = Time Period involved in months or years
From the base formula, A = P(1 + rt) derived from A = P + I and I = Prt so A = P + I = P + Prt = P(1 + rt)
