Explanation:
So what is
Let's turn it into an equation, but here are a couple things to remember:
- Use a variable for what you're solving. I'm going to give the thing we don't know the variable
#x# . - The word "is" means "equals", so wherever you see that word, you can use an
#=# sign. - The word "of" means "times", so you can use a
#xx# sign for that word. #80%# is the same thing as#80/100 rarr 8/10# as a fraction or#0.8# as a decimal. I will be using the fraction form in the equation.
