Answer:
I would rather do the second option of which uses Compound interest that will give a profit of $47.85
Step-by-step explanation:
In this problem we will be exploring the two formulas
1. simple interest
A= P(1+r*t)
2. compound interest
A= P(1+r/n)^nt
Where A= final amount
P= initial amount
r= rate
t= time.
n= number of periods Compounded
1.given data
P= $600
r= 3%= 3/100= 0.03
t= 2 years
A= 600(1+0.03*2)
A= 600(1+0.06)
A= 600(1.06)
A= $636
Interest = 636-600= $36
2. Given data
P= $600
r= 4%= 4/100= 0.04
n= 24
t= 2
A= 600(1+0.04/24)^24*2
A=600(1+0.0016)^48
A=600(1.0016)^48
A= 600*1.07975
A= 647.85
Interest = 647.85-600= $47.85
15% = 0.15
15% of 71.85 is equal 0.15*71.85 ≈ 10.78
Answer: 18.66km
step by step:
2.41km + 15.8 km + 0.45 km
= 18.66 km
Answer:
504
Step-by-step explanation:
Using the definition
n
= 
where n! = n(n - 1)(n - 2).... × 3 × 2 × 1
Thus
9
= 
← cancel the terms of 6! on numerator/denominator, leaving
= 9 × 8 × 7 = 504
