Question 708852
Hello, 
(Hint: The key to getting A's in school is understanding the words and symbols.)
Notice two small words in 15% off of $6.25  -- "off & of"
"Of" in math means multiply. 
"Off" means subtract. 
So 15% off of $6.25
Multiply .15 times $6.25 to get: $.9375 (rounded to $.94)
Subtract .94 from $6.25 to get:
$5.31
Make sense?
