C = .25t +3.50 in 'C' dollars for 't' minutes. How much does it cost to rent the canoe for 1 hour?​
yKpoI14uk [10]

Answer and Step-by-step explanation:

We know that t is in minutes, and 1 hours is equal to 60 minutes, so we plug in 60 for t.

C = 0.25(60) + 3.50

C = 15 + 3.50

C = 18.50

At the end of 8 years, Anna paid $400 interest for a loan. If the simple annual interest rate was 4%, how much did Anna borrow?
Valentin [98]

Answer:

$1,250

Step-by-step explanation:

You can find the answer using the following formula:

i = Prn

i= interest= $400

P= principal

r= rate of interest=0.04

t= time periods= 8

You can replace the values you have in the formula and then, isolate P:

400= P*0.04*8

400=P*0.32

P= 400/0.32

P= 1250

According to this, the answer is that Anna borrowed $1,250.
