Rachel wants to buy a shirt regularly priced at $32. it is on sale for 40% off. rachel estimates that she will save 2/5 of $30 or $12. will the actual amount be more or less than $12? explain. i need this done today so me now !

Okay, so first you know that the shirt was priced at $32.
It's on sale for 40%. 
40% =  
Now we can make a proportion, so set the values in a fraction.

We put 32 on the bottom since it's the total amount.
Divide 100 by 32, so 100÷32=3.2
Now divide the numerator (40) by 3.2, so 40÷3.2=12.5
That means the new cost of the shirt is $12.50 so the new amount will be more than 12 dollars. 
Hope that helped :)
