Answer: Check Explanation Below ;)
Explanation:
A: To find the decimal value, we just need to convert 46% into a decimal is the marked down/sale price was reduced by 46%. 46% in decimal form is 0.46
B: Two expressions would be 0.46b+0.56b=1b and 1b-0.46b=0.56b. This is since the 46% is removed from being on discount, you would only have 56% of the original product price.
C: If $29 was the original price, we can divide $29 by 100 and get $0.29. Then we could multiply that by 56 and get $16.24 as our discounted price. This is since 46% is gone from the new price meaning the $16.24 was 56% of the original price.
D: Looking at our second expression, we can subtract 29 (1b) by 16.24 (0.56b) and get the (0.46b) value. The difference of 29 and 16.24 is $12.76. That means you would save 46% or $12.76 off the order with the discount which sounds like a pretty good deal.
Hope that helped a lot. Let me know any further questions.
