Answer: If it is 10.4 the answer would be 170.56 if it is 140 the answer would be 162,323.2, though I think it is<em><u> 170.56</u></em>
Step-by-step explanation:
Whats the question? The cheapest is B and 10 percenct off is 900 on that 1,000 and A is 50 $ more expensive then B
First do 12-5, which equals 7. Next, subtract 1/10 from 2/5. 2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2. 4/10-1/10=3/10. Now add 7 and 3/10. You will get 7 3/10 as the answer, which is letter C.)
