To determine a percentage difference, simply divide the difference of the two numbers by the original. For instance, 82-65.60=16.4 16.4 is 20% of 82, so the discount is 20% (16.4/82)
1) 200 candies
15% of my candies were strawberry candies. I had 30 strawberry candies. How many candies did i have?
-----
Let "x" be the number of candies.
----
Equation:
0.15x = 30
x = 30/0.15
---
Multiply numerator and denominator by 100 to get:
------------------
x = 3000/15
----
x = 200
---------------------------------
2) 146 STUDENTS
27%*T=54, So T=200.
So 200-54=146 Students passed the test.
---------------------------------
3) She got a 20% discount (or 80% discount). (Work shown for 80%).
First you have to find out how much Mandy paid. So from 15000 you will subtract 3000. 15000-3000=12000.
Next you need to set up your equation. . You then have to cross multiply. So 100 times 12000, 100*12000=1200000. And 15000 times x is 15000x. Finally you divide both sides by 15000. And 1200000 divided by 15000 is 80. X=80
