Step-by-step explanation:

Step 1 : Write the formula for calculating simple interest.

Simple Interest = P x R x T

100

P: Principal Amount-The loan taken (30,000)

R: Interest rate at which the loan is give (6)

T: Time period of the loan in years-there are 12 months in 1 year. There are 7 months from May till June (7/12)

Step 2: Substitute values in the formula

Simple Interest = 30,000 x 6 x 7/12

100

Simple Interest = $1050

Step 3: Calculate the amount due at maturity

At the maturity or the end of the time period given, the original or principal amount of the loan has to be repaid along with the simple interest.

salantis [7]

Answer:

$7,986.25

Step-by-step explanation:

We can use the following formula to solve:

$A=P(1-r)^t$

P = principal value

r = rate (decimal)

t = time (years)

First, change 15% into a decimal:

15% -> $\frac{15}{100}$ -> 0.15

Since 2015 and 2020 are 5 years apart, we will use 5 for t. Now, plug the values into the equation:

$A=17,999(1-0.15)^5$

$A=7,986.25$

Your car would be worth $7,986.25
