How much did Dylan receive from the bank? $ State your result to the nearest penny. What was the actual rate of interest? % State your result to the nearest hundredth of a percent.

actual rate of interest is 2.08 %

Step-by-step explanation:

Given data

borrowed = $2100

time = 15 months

rate = 2.6%

to find out

interest and receive from the bank and actual rate of interest

solution

we know bank discounted the loan at 2.6%

so interest will be 2.6% of $2100

that is = 2.6/100 * 2100

interest = $54.60

so receive from the bank is borrowed money - interest

receive = 2100 - 54.60

receive from the bank is $2045.40

and we can say that interest is directly proportional to time

so interest of 12 months / interest of 15 month = 12 month time / 15 month time

here interest of 12 months = 12/15 * interest of 15 month

interest of 12 months = 12/15 * 54.60

interest of 12 months is $43.68 (annually)

now we can calculate actual rate of interest

that is = interest / borrowed money * 100

actual rate of interest = 43.68/2100 * 100

actual rate of interest is 2.08 %
