Your bank gives you a special loan of $112,000. At the end of 30 years, you will pay the bank $176,400 in simple interest. What is the annual interest rate on your loan?

Answers

woah
that's alot of interest

ok so simple interest is the same every year
therefor if the total interest is 176400 in 30 years, then the interest for 1 ear is 176400/30=5880

ok so now
112000 times x%=5880
percent means parts out of 100 so x%=x/100

112000 times x/100=5880
112000x/100=5880
1120x=5880
divide both sides by 1120
x=5.25
answer is 5.25%

Interest , I = PRT/100

R = 100I / PT.

P = 112 000. T = 30 years. Interest = 176 400.

R = 100 * 176 400 / (112 000 * 30)

R = 5.25

Rate = 5.25% per year.

Increase £2 by fifty percent.(Show working out)

Answers

If I were to increase 2 pounds by fifty percent, I would increase it by half of its value.
Half of 2 is 1, therefore I would increase 2 pounds by 1, thus increasing it to a grand total of 3 pounds. I hope this helps, have a nice day, and if you need more help just ask! :)

First, find out the 50% of £2 then add it to £2 for final value.

It would go in like this -

Increment =50% of £2
= 50/100 × 2
= £1

Now, final value = £1 + £2 = £3
