If 15 equals 1/3 of the population then 2/3 will be over 20. Multiply 15 by 2 to equal 30, the 2/3 over 20. Total population counted will be 45 (15 + 30).

First convert your fractions into decimals. From there you want to multiply your decimals together, and then subtract that total from 20. That should give you X. So, 7/3 translates into 3 1/3, which becomes 3.33. 98 becomes 1 1/8 which translates to 1.25. Multiplying these gives you an answer of 3.74625, which can be rounded up to 3.75.now subtract 3.75 from 20 and you should get 16.25. This is X.

Oh geeze,, you have 480 ladybugs in all?!!!

That makes a total combined population of 1,680 critters!

And why did you only take a 1.25% sample?!!

But maybe ladybugs like living in dirt piles better than other backyard areas, so you might not have that many! ;)

There is no such button. You must figure out the formula and enter it, giving the appropriate value for the annual interest and the number of years (15).

Since he has $20,250, he should put $4050 into each drawer.

To get the total amount, multiply 650 by 20 and 725 by 10, then add the two numbers together. To get the final result, divide the total by 5. Since you didn't specify the make and model of your calculator, I'm afraid I can't give you the sequence of button presses to calculate this.

It uses an odd notation. For 10 + 50% you need to press 10 [x] 50 [%][+] and it will display 15. For 144 + 60%, you need to press 144 [x] 60 [%] [+] and it will display 230.4 which is the correct answer. Now tell me what the ? key is for because I haven't figured that one out yet,

Example if you want to charge a person 8% of $20 dollars just multiply 20*1.08=21.60 and that gives you the total amount to charge them.

If your total amount is 20 and you charged 8% and want to know the before tax amount you do the opposite 20/(1.08)=18.52

If your total amount is 20 and you charged 8% and want to know the before tax amount you do the opposite 20/(1.08)=18.52

Big calculators work a little different than handheld calculators. Like the above commentor explained, if you have a basic "whats 100 minus 20?" You have to entered as 100 + 20 -- And when you hit the minus button at the end, it will give you the total. 100 is the positive number, and the 20 is the negative number that your subtracting. Also you can hit 20 -- 100 + and get the same total because you entering 20 as the negative and 100 as the positive, just in reverse.
