$30 board game on sale for 20.10 what is the discount

assuming 20.10 is the sale price,

20.10/30.00 = 0.67
That is, the sale price is 67% of the full price
so, that's a 33% discount

how did you get 33 your answer is correct but i just want to know how Thanks!

To calculate the discount for the board game, you need to find the difference between the original price and the sale price. Here's how you can do it:

1. Subtract the sale price from the original price: $30 - $20.10 = $9.90.

So, the discount for the board game is $9.90.

Assuming 20.10 means consecutive discounts of 20% and 10%

what is 30(.8)(.9) ??

notice the order of the discounts would not matter.
