Answer:
The sale price for the donuts is $10.8
Explanation:
Normal cost of donuts = N = $12
Now, there is a 10% discount so, we have to find what the price will be after subtracting 10% of the price.
This just comes to be 90% of the original price,
i.e. 10% discount means that the product is now sold at 90% of its original value.
Hence,
Sale Price = S = (90%)(Normal cost of donuts)
S = (0.9)(12)
S = 10.8
S = $10.8
