State your problem please?

Didnt stump you for a second, thought i could  good game! 

Theres so many different kinds of those....

Here i found this website, maybe it will help?

Hearing aids? Q-phones? 

could you be more specific? 

also remember, to convert a fraction to a decimal;

If it is a one digit number, it will be in this form. 0.0#

If it is a two digit number, it will be in this form. 0.#

If it is 100%, it will be 1.0

If it is past 100%, such as 280%, it will look like this. 2.80

well when your finding a percent of any number its pretty simple.

Here is the equation for this problem.

0.05*90=5% of $90

do the math, 90*.05=4.5

4.5 would be your answer. 

When finding a percent of a number, convert the percent into a decimal and multiply it by the whole number.

Examples

10% of 50 = 0.10*50

7% of 20 = 0.07*20

Hello guest, welcome to Web.2.0 =)

A=P(1+r/n)^nt  

This would be the formula for finding compound interest.

P would equal how much you borrow or deposit.

r would equal a decimal of your rate of interest

t would equal how many years your borrowed or deposited value has been in/out for

n would equal how many times the interest was compunded in a year

A would equal the ammount of money and interest owed/accumulated in n years

Sorry this is late '=)

actually, 0/0 could be infinity because 0 can go into 0 and infinite amount of times because neither numbers have any value 

Derp! =b 

how does reporting a mod work? 

that is an inapropriate response to this question 

first, convert both fractions into improper fractions. for the 5 simply put a 1 as the denominator! and for 4 and 2/5 just multiply 4 by 5 and add two (now its 22/5) 

now we will need too find the lcd, which is 5

our new fractions are 25/5 and 22/5

multiply these two fractions too get your answer

he or she may not know how to solve the equation 

P.s, S is the number of sales she needs to make! and if you get a decimal, just round to the nearest number 

Well the first question is simple! find the equation that could equal 1021 dollars, note in A at the end of 13.25 there is an s, this s is an unknown number that 13.25 will be multiplied by. so if we subtract 650 from 1021 we will find how much more we need. 1021-650= 371. so divide 650 by 13.25 and you will find S
