From the question, we are informed that the scale for a map to actual distance is 2 cm to 100 mi and that the driving distance on the map between Los Angeles and Las Vegas is 5.4 cm.

T.J. Had a car loan for $5800. Over the course of the loan, he paid a total of $1508 in interest at a rate of 6.5%. Over how man
kodGreya [7K]

Answer: it took T.J. 48 months to pay the car loan.

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P = principal or amount loaned

R = interest rate

T = time in years.

I = interest

From the information given,

P = $5800

R = 6.5%

Over the course of the loan, he paid a total of $1508 in interest. Therefore,

I = $1508 Therefore,

1508 = (5800×6.5×T)/100

1508 = 377T

T = 1508/377 = 4 years

Assuming there are 12 months in a year, the number of months in 4 years would be 4×12 = 48 months
