slamgirl [31]

Answer:

4 3/16 miles a day

Step-by-step explanation:

16 3/4 miles in 4 days

Divide 16 3/4 by 4

16 3/4 = 67/4

4 = 4/1

To divide you multiply by the reciprocal(flip of the numerator and denominator)

67/4 ÷ 4 = 67/4 x 1/4 = 67/16

67/16 = 4 3/16

If my answer is incorrect, pls correct me!

David express company was asked to deliver 325 boxes of apples. according the rule, the delivery fee is
Andrew [12]

Answer:

22 boxes were lost.  Look for the happy squirrels.

Step-by-step explanation:

Let x be the number of lost boxes.  David Express should expect to receive  $25 for each of the 325 boxes of apples.  That means:

($25)*(325) = $8125

The loss of a box means that the delivery fee would be forfeited, which would amount to:  x*($25)

But a compensation fee of $75/box also applies, so the total loss to the income would be x*($25+$75) or x*($100).  This would be subtracted from the total expected income of $8125:

Resulting Income:   $8125 - ($100)x = $5925

$8125 - ($100)x = $5925

$8125 - ($100)x = $5925

-100x = -2200

x = 22 boxes were lost.                    Zounds! [A metric term for %$%^&]

===================

<u>Check:</u>  Does the loss of 22 of the 325 boxes result in a total payment of $5925?

Delivered boxes:  (325 - 22) = 303 boxes delivered.  303*$25 = $7575

Penalty of $75 per lost box:  22*($75) = $1650

Result:  $7575 - $1650 = $5925  <u>YES</u>
