She put all the addresses in a bag and drew a random sample of 25 addresses. She then asked those families if they would volunteer to help at the shelter. She found that 18% of the families would volunteer to help at the shelter. She claims that 18% of the neighborhood families would be expected to help at the animal shelter.

nicole ordered a volleyball for 9.75 a net 29.99 and knee pads for 15.00. Nicole's mother said she will pay for the order on her credit card if Nicole gave her the money Nicole gave her mother $40 her mother also applied the money that she owed Nicole for babysitting Nicole's mother then gave her back $5.26 how much did Nicole's mother owe her for babysitting

Answers

To solve a kind of question like this and to have a better understanding while solving it. It is pertinent to list out the parameters given:

List of Items bought by Nicole:

Volleyball = $9.75
Net = $29.99
Knee pads = $15.00

If Nicole gave her mother the money $40 for babysitting, and:

Her mother paid back $5.26 out of it.

Then, the total amount of money Nicole's mother owed Nicole can be calculated by adding the items Nicole bought with the amount her mother paid her back, then we will subtract the total amount from the money Nicole gave her mother for babysitting.

Mathematically, we have:

= $(9.75 + 29.99 + 15+ 5.26) - $(40)

= $60 - $40

= $20

Therefore, we can conclude that the amount of Money Nicole's mother owed Nicole for babysitting is $20

To figure this out just add:

9.75 + 29.99 + 15 + 5.26 = $60 Since this is $20 more than Nicole gave her mom that means she made $20 baby sitting. There's your answer!
