Answer: $524.30 (choice B)
========================================================
Step-by-step explanation:
If you save 30%, then you pay the remaining 70% which converts to the decimal form 0.70
70% of $749 = 0.70*749 = 524.30
----------
Or another way to look at it is to calculate how much you save
30% of 749 = 0.30*749 = 224.70
You save $224.70 and the final price is 749 - 224.70 = 524.30
