Answer:
16 cities
Step-by-step explanation:
if 5days = 10 cities
8days=?
applying cross multiplication :
(8days × ten cities )÷5 day
= 16 cities
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Cross multiply
(4/9)(9)(36) = (x/36)(36)(9)
(4)(36) = (x)(9)
Simplify
144 = 9x
Isolate the x. Divide 9 from both sides
144/9 = 9x/9
x = 144/9
x = 16
16 is your answer
hope this helps
Answer:
Harrison method results in more money after 2 years
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
Harrison Method
![t=2\ years\\ P=\$300\\ r=0.02\\n=12](https://tex.z-dn.net/?f=t%3D2%5C%20years%5C%5C%20P%3D%5C%24300%5C%5C%20r%3D0.02%5C%5Cn%3D12)
substitute in the formula
![A=\$300(1+\frac{0.02}{12})^{12*2}=\$312.23](https://tex.z-dn.net/?f=A%3D%5C%24300%281%2B%5Cfrac%7B0.02%7D%7B12%7D%29%5E%7B12%2A2%7D%3D%5C%24312.23)

substitute in the formula
![A=\$200(1+\frac{0.04}{4})^{4*2}=\$216.57](https://tex.z-dn.net/?f=A%3D%5C%24200%281%2B%5Cfrac%7B0.04%7D%7B4%7D%29%5E%7B4%2A2%7D%3D%5C%24216.57)
therefore
Harrison method results in more money after 2 years
Answer:
We know Mr. Jackson will have to pay 0.55 dollars per mile and that he's traveling 61 miles, so, if we want to know. how much will he pay, we can multiply the quantity of miles (61) per the cost of these:
0.55 * 61 = 33.55
So we know he will have to pay 33.55 dollars, and, as the travel is round, considering he will travell the same quantity of miles, he will pay twice
33.55 * 2 = $67.10
He has more budget than the needed for the travel
