For example:

say the cost of the pillow is 20 dollars and including 10% interest. How much money did you have to pay?

first, you have to change 10% into a decimal, which would be .10

then, you multiply .10 with 20. then you would get 2.

2 dollars would be the interest.

and to see how much you would pay for the pillow including interest, just add 20 dollars to your 2 dolllars.

and so you would pay 22 dollars all together.

Another example:

Say you see something that you know was purchased for $32.30 and the original cost was $38.00 and you want to know what percentage the discount was.

If you divide the $32.30 by $38.00, you will get .85. You then subtract that from 1.00 (which represents the 100%), and it will give you .15, or 15%.

How is math used in career of banker?

well... bankers use math all the time. they use it to find the interest. example: the person borrows 1000 dollars from the bank and say the interest is 2% monthly, so the banker can use math in that case. Also, when the banker invests on things, they use math to predict what their profit is, it can be negative ( a loss of money) or they can gain.

Compound interest of 2 year is rs 156 and 3 year is rs 254 What is rate of interest?

Oh, dude, you're hitting me with the math questions now? Alright, let me break it down for you. So, if the compound interest for 2 years is Rs 156 and for 3 years is Rs 254, that means the interest for the third year is Rs 98 (254 - 156). To find the rate of interest, we need to calculate the interest for the first year, which would be half of the interest for 2 years (Rs 78). Then, we can divide this by the principal amount and multiply by 100 to get the rate of interest. Math can be fun, right?


How do you answer the interest problem about math?

The first thing you have to do is read the problem, so that you know what information it gives you, and you understand what it's asking you. We need the same facts before we can do anything with it, and you haven't told us anything. The only guess we can make from what you've given us is that it's probably a math problem about interest, not an interest problem about math.
