Kelsey had $65 to spend on books. Each book cost $5. 50, and there was a $7. 50 fee for shipping. She let b equal the number of

books she can purchase and wrote the inequality 5. 50 b + 7. 5 less-than 65 to represent the situation. Which statements describe the reasoning used to determine if kelsey’s inequality is correct? select two options. The inequality symbol is correct because she must spend less than $65. The inequality symbol is incorrect because she can spend up to and including $65. The expression 5. 50b + 7. 5 is correct because $5. 50 per book is 5. 50b and that is added to the shipping fee of $7. 50 to determine the total purchase price. The expression 5. 50b + 7. 5 is incorrect because $5. 50 per book and $7. 50 should be combined to $9. 50b to determine the total purchase price. The inequality symbol is correct because she cannot spend more than $65.

Answer:

The inequality symbol is incorrect because she can spend up to and including $65.

The expression 5. 50b + 7. 5 is correct because $5. 50 per book is 5. 50b and that is added to the shipping fee of $7. 50 to determine the total purchase price.

Explanation:

The inequality should be 5.50b + 7.5 ≤ 65 because she can use less than $65 or all $65 to spend on books.

Also, the shipping fee is for all the books she buys combined, not for each individual book so the left side of the inequality should read 5.50b + 7.5.

densk [106]

The tool that can make chart 1 look like chart 2 is the data labels

<h3>What are Charts?</h3>

Charts are graphical ways of representing data elements.

Charts can be in form of:

  • Graphs
  • Tables

From the diagram (see attachment), we can see that:

  • Both charts are circle graphs
  • The data label of chart 2 is visible, while the data label of chart 1 is not

So, the data label of chart 1 has to be made visible, for the chart to look like chart 2

Hence, the tool that can make chart 1 look like chart 2 is the data labels

Salutations!

<span>Last month Sarah Ryan and Taylor received a total of 882 emails. If Sarah receive 25% more emails than the sum of the numbers of emails received by Ryan and Taylor. How many emails did Sarah receive?

Lets solve this!

Let the sum of the number of email received by Ryan and Taylor be "x" and "y".

Sarah + Ryan + Taylor = 882 emails.

Sarah = 25/100 ( x+ 7)

Sarah = 25 + x + y/100 = 882

Now, isolate the numbers carefully ---

Sarah = 25 + x + y = 822 </span>× 100

Sarah = 25 + x + y = 82,200.

Sarah = x + y  = 82,200 - 25

Sarah = x+ y = 82,175.

Sarah received 82,175 emails.

Hope I helped (:

Have a great day!
