The answer is 700 feet, because if you divide 5,280 feet by 1 mile you get 88 feet per second, then you multiply 88 feet by 8 seconds you get 704 feet. Since the question said "about" I am assuming that means rounding. You round 704 to 700 and that's how you get the answer.
Answer:
62 newspapers
Step-by-step explanation:
Let s represent the number of Sunday papers sold. Then s/2 is the number of Friday papers sold. The total revenue is ...
1.50s + 0.75(s/2) = 116.25
1.875s = 116.25 . . . . simplify
s = 116.25/1.875 = 62 . . . . . divide by the coefficient of s
62 Sunday papers were sold.
To solve this problem, we must multiply the cost of one box of chocolates ($9) by the number of boxes of chocolates purchased (15) to find the total cost of the chocolates.
$9 * 15 = $135
Therefore, your answer is $135, or option D.
