The cake store is having a 10%, percent off sale on all of its cakes. if the cake you want regularly costs $6, how much would you save with the discount?

Here is a pro tip! When taking 10% of anything move the decimal back ONCE. The number you get is 10% of that number. You then take that number and subtract it by your original number if you want to know how much it will cost if it was 10% off. 

The reason why that works is because to take 10% of something you would need to multiply it by 0.1, which is the same as 1/10 (which is also the same as dividing the number by 10). 

So you take 10% of $6.00. It's $0.60. 
Subtract that from your original amount.

 $6.00
-$0.60

I'll let you do that one, but the answer comes out to be: 

$5.40

Now to answer the question of this problem (the previous steps were if they asked for the price, but in this case you could've stopped at the 10% part) 

You save $0.60.

$5.40 would be how much you pay

$7.50x+$4.50y=midk it's been awhile since i've done one of these
