Answer:
40
Step-by-step explanation:
If Whitney was driving x speed, her mother was driving x+5. Multiply that by the distance each traveled, and you have an equation that looks like this:
8(x+5) = 7(x)
Simplify it and you get:
8x + 40 = 7x
Now solve regularly:
8x-8x + 40 = 8x - 7x
40 = 1x
40 = x
Whitney's speed: 40
Her mother's speed: 45

Answer:
=$23,350.802
Step-by-step explanation:
Compound Interest (A)=P(1+r/n)^nt
Where,
P=principal=$20,000
r=Interest rate=7.77%=7.77/100
=0.0777
n=number of periods=12 month in a year
t=time=2 years
(A)=P(1+r/n)^nt
=$20,000(1+0.0777/12)^12×2
=$20,000(1+0.006475)^24
=$20,000(1.006475)^24
=$20,000(1.1675401)
=$23,350.802
