More on a percentage question 
20070823 

Dee pose la question : In a previous question, you answered:
"What percentage of $34.51 is $10.71?
I translate this English statement into a mathematical statement (equation) using the following
"what" is the unknown, call it x
"percent" is peronehundred, that is over 100
"of" is multiplication
"is" is the verb, which in an equation is the equal sign
Thus the English statement above becomes
x/100 $34.51 = $10.71
Solving for x yields
x = 31.03
Hence the gross profit is 31% of your selling price."
How did you solve for 'x' Penny Nom lui répond.
