BigorU [14]

Answer:

Step-by-step explanation:

Alice borrowed 16700 from the bank at a simple interest rate of 9% to purchase a used car. It means that the interest is not compounded. Simple interest is usually expressed per annum. The formula for simple is

I = PRT/100

Where

I = interest

P = principal(amount borrowed from the bank)

R = 9% ( rate at which the interest is charged

T = number of years

At the end of the loan,she had paid a total of 24215. This means that the interest + the principal = 24215

Therefore,

The interest = 24215 - 16700 = 7515

Therefore

7517 = (16700 × 9 × t)/100

751700 = 150300t

T = 751700/150300

T = 5 years

Converting 5 years to months,

1 year 12 months

5 months = 12 × 5 = 60 months

Ricardo has saved 83% of the money he needs to buy a new skateboard that costs $150. How much MORE does he need to save to buy t
4vir4ik [10]

Answer:

17%, or $25.50

Step-by-step explanation:

If Ricardo has already saved 83% of the money, then he needs to save 17% more, because 83% + 17% = 100%

So what you need to do to figure out the answer is to find out 17% of $150

You first have to convert 17% into decimal form which is 0.17.

Then, you multiply 0.17 × 150 = 25.5

Ricardo needs $25.50 to buy the skateboard.

Hope this helped.

Mr. Sammie has now decided to expand his food truck business. Based on the information in the chart below, what Region will be b
Nady [450]

Answer:

SouthEast region

Step-by-step explanation:

#We need to find the truck density per region to be able to determine the most viable region for business:

Density=\frac{mass}{Area}\\\\d_{NW}=\frac{320}{10972}=0.0293\  truck/sq \ mi\\\\d_{NE}=\frac{400}{9485}=0.0422\ truck/ sq \ mi\\\\d_{C}=\frac{480}{11645}=0.0412\ truck/sq \ mi\\\\d_{SW}=\frac{515}{11589}=0.0444 \ truck/sq \ mi\\\\d_{SE}=\frac{250}{9933}=0.0252 \ truck/sq \ mi

SouthEast region has the lowest density of 0.0252 truck/sq mi hence the best region for expansion.

-A low food truck density is an indicator of a relatively low competition hence existance of a large market share yet to be dominated.
