Harper borrowed $6,200 from the bank. 1 year later, Harper owes the bank $6,696. What was the percentage rate of simple interest
Fofino [41]

The rate of simple interest for loan was 8%

Step-by-step explanation:

Given

Principal amount = p = $6200

Time = t = 1 year

Amount after interest = $6696

We have to calculate the amount of interest first

So,

Interest amount =I= Amount after interest - principal amount

= 6696-6200

=$496

The formula for simple interest is:

I =prt\\Here\\r\ is\ rate\\p\ is\ principal amount\\t\ is\ timePutting\ the\ values\\496=6200*r*1\\r=\frac{496}{6200}\\r=0.08\\r=0.08*100\\r=8\%

The rate of simple interest for loan was 8%

Eric plans to rent a car for a day from Easy Car Rental. He has a coupon for 25% off the daily base rate of $40. He will also ha
Volgvan
In this situation, there are 2 separate terms (parts of the story).  The first part is the information about the coupon that applies to the daily rate of $40.  You will represent this as 0.75 (for the 75% that you will be paying) x 40.  (The other part of this story is that you are paying $0.15 per mile which is represented as 0.15m.  You need to put these together to get 0.75(40) + 0.15m.  The 0.25 times 40 can be simplified to say 30, so write it as $30 + $0.15m.
