Answer:
D. $26,743.80
Step-by-step explanation:
25230(1+ .06(1))
type that in a calculator and you will get the correct answer of D.
Also I literally learned this 5 minutes ago and my teacher said I was correct.
7 and 10 is half
so we expect the people come to wedding half of 120÷2=60 people
i just try
S=d/t ⇒d=s*t
s=speed
d=distance
t=time
The first train :
d=x
x=70 miles/h*t ⇒ x=70t (1)
The second train
d=360 miles - x
360 miles - x=80 miles/h*t ⇒360-x=80t ⇒ x=360-80t (2)
therefore, with the equations (1) and (2) we have a systeme of equations:
x=70t
x=360-80t
we can solve this system of equations by equalization method.
70t=360-80t
70t+80t=360
150t=360
t=360/150=2.4 (≈2 hour 24 minutes)
Answer: the first train meet with the second train in 2 hour 24 minutes.
