Step-by-step explanation:

to take sweepstakes for the largest pumpkin crop at the Riverside County Fair the average weight of Ethan's to pumpkins must be greater than 875 lb one of his pumpkins is 903 lb what is the least amount of pounds II pumpkin could weigh in order for Ethan to win the prize​

Answers

Answer:847 pounds

Step-by-step explanation:

Let w be the weight of the second pumpkin.

Given that weight of first pumpkin is 903 pounds.

Since we need the weight of the second pumpkin to be minimum,the average weight of the two pumpkins must be just equal to the required weight to win.

Given that the required weight to win is 875 pounds.

So,875=(w+903)/(2)

1750=w+903

w=847 pounds

Katye received $100.
Katye buys a $23 book
Katye wants to donate $10 to each charity
Katye wants to donate to as many charities as possible.

Answers

Answer:

Katye will be left  with $7  if she donates to as many charities as possible

Step-by-step explanation:

The total number of gifts Katye received = 15

The total amount in cash she received = $100

The cost of the book purchased from the gift amount = $23

So, the money left with her = Total money - Cost of the book

= $100 - $23  = $77

So, she still has $77 left with her.

Now, she wants to donate $10 to as many charities as she can.

\textrm{Number of charities she can donate to} = \frac{\textrm{Total  amount to be donated}}{\textrm{Amount donated to each charity}} \n = (77)/(10)  = 7.7

As 7.7 is NOT a WHOLE number. So let us take the nearest smaller whole number to 7.7  which is 7.

Hence, she can donate to 7 charities.

Amount donated to 7 charities = 7 x $10 =  $ 70

⇒ The money left with Katye  = Total money to be donated - Donated amount = $77 - $70    =  $7

Hence, Katye will be left  with $7  if she donates to as many charities as possible.

Answer: The answer is: How much money will Katye have left after buying the book and making donations? and the other answer is :

B.Katye received $100.

C.Katye buys a $23 book.

D.Katye wants to donate $10 to each charity.

E.Katye wants to donate to as many charities as possible.

Step-by-step explanation: so it's D the last
