After working for 24 hours,zoe made $234. After working for 40 hours, zoe made $390.predict how much she would make after 10 hours of work?

Answers

First you need to find money per hour. 234 ÷ 24 = 9.75; 390 ÷ 40 = 9.75; she makes $9.75 an hour. Multiply by ten; in 10 hours she'll make $97.5. Hope that helps!

Final answer:

To predict how much Zoe would make after 10 hours of work, we set up a proportion using the information given in the question. Cross multiplying and solving for x, we find that Zoe would make $97.50 after 10 hours of work.

Explanation:

To predict how much Zoe would make after 10 hours of work, we can use the information given in the question. We know that after working for 24 hours, Zoe made $234, and after working for 40 hours, Zoe made $390. To find out how much Zoe would make after 10 hours of work, we can use the concept of proportionality. We can set up a proportion using the number of hours worked and the amount earned:

24 hours / $234 = 10 hours / x

Cross multiplying, we get 24x = (10 * $234). Solving for x, we find that x = (10 * $234) / 24. Evaluating the expression, we find that x = $97.50.

Tyler reads 2/15 of a book on Monday 1/3 of it on Tuesday 2/9 of it on wensday,and 3/4 of the remainder on Thursday, if he still has 14 pages left to read on Friday, how many pages are there in the book

Answers

Answer:

129 pages.

Step-by-step explanation:

Let's call p the total number of pages.

He reads (2)/(15)p on Monday. There are 13/15 left.

(1)/(3)p on Tuesday. There are 2/3 left.

(2)/(9)p on Wednesday. There are 7/9 left.

Now, the remainder would be the difference between p and all pages read at this point

p-(2)/(15)p-(1)/(3)p-(2)/(9)p=(45p-6p-15p-10p)/(45) =(14p)/(45)

So, 3/4 of this is

(3)/(4) * (14p)/(45)=(42p)/(180) =(21p)/(90)=(7p)/(30)

The sum of all pages read is

((2)/(15)+(1)/(3)+(2)/(9)+(7)/(30) )p+10=p\n((12+30+20+21)/(90))p +10=p\n(83)/(90)p+10=9\n 10=p-(83)/(90)p\n10=(90p-83p)/(90)\n 900=7p\np=(900)/(7)\n p \approx 129

Therefore, there are around 129 pages.
Since Tyler read 3/4 of the remainder, that means 14 pages must be 1/4 of the remainder.

4x14=56 pages

Similarly, 56 pages should be the remainder after he read 2/9 of the book on wednesday.

So, 1-(2/15+1/3+2/9)=14/45

If 56 pages is 14/45 of the whole book,
56 / (14)/(45) = 180
The book is 180 pages.

Elizabeth, Heather, and Erin share the same birthday. They’ve decided to join together to have one big birthday party. The event location says it will cost $70 for the rental of the space and $15 per guest. Each girl invites x number of guests, including themselves in their guest count.The girls have each written a different correct expression to represent the total cost of the party. EXPLAIN how each of the 3 expressions below represents the total cost.
(a) Elizabeth’s expression: 15x + 15x + 15x + 70

(b) Heather’s expression: 15(x + x + x) + 70

(c) Erin’s expression: x(15 + 15 + 15) + 70

Answers

Elizabeth finds the cost of each girl's guests and adds the rental cost, for a result of the total cost.

Heather multiplies the cost per guest by the total number of guests, and adds the rental cost.  This has the same result.

Erin multiplies the amount of guests each girl invites with the price per guest, taking the price three times since three girls invite guests.  Then, she adds the rental cost.

Thus, all three equations are equal to the costs of the guests added to the rental cost, which is the full cost.

The sales tax on a Camera is $5.60, which is 8% of the total price. What is the price of the camera?

Answers

The amount of sales tax that is taken on the camera = $5.60
Percentage of sales tax taken on the camera = 8%
Let us assume the actual price of the camera = x dollars
Then
(8%) * x = 5.60
(8/100) * x = 5.60
2x/25 = 5.60
2x = 5.60 * 25
2x = 140
x = 140/2
   = 70 dollars
So the actual price of the camera is $70. I hope the procedure is clear enough for your understanding. You can use this method for solving similar problems in future without requiring any help from outside.
