PLEASE SHOW WORK

Answers

Answer:

12.5%

Step-by-step explanation:

12.5 %
100% = 200
x% = 25
100% = 200(1)
x% = 25(2)
100/x% = 200/25
x%/100% = 25/200
x = 12.5% 25 is 12.5 percent of 200

The manager of a bookstore ordered 480 copies of a book. The manager paid a total of $7,440 for the books. The books arrived at the store in 5 cartons. Each carton contained the same number of books. A worker unpacked books at a rate of 48 books every 2 minutes. The manager unpacked books at a rate of 54 books every 3 minutes.

How many minutes did the worker need to unpack 200 books?

Enter your answer, as a decimal rounded to the nearest hundredth, in the space provided.

Please Help Meh

Answers

So 48 • 4 would equal 192 so 4 • 2 mins equals 8 mins and then you have 8 more books to unpack so 48 divide by 8 equals 6. So the answer would bc (8 mins and 6 second)

Deb earned a total of $20 by selling 10 cups of lemonade. After selling a total of 14 cups of lemonade, how much money will Deb have made in all? Assume the relationship is directly proportional.

Answers

Deb would have made $18 from selling 14 cups of lemonade. She earned $20 for selling 10 which is $2 per cup. Add $2 dollars for 4 more cups which makes $18

Deb earned 20 dollars from 10 cups of lemonade so 2$ per cup
She sells 4 more so 8 more dollars.
20+8=28
Deb made 28$ in all

Solve for Variable: 3x + 7 < 16
A. x > 3
B. x < 5
C. x > 6
D. x < 3

Answers

Answer:

D. x < 3

Step-by-step explanation:

3x + 7 < 16

To solve, we have to isolate x.

3x + 7 < 16

Subtract 7 from both sides :

3x < 9

Divide 3 from both sides :

x < 3

Now in some cases, you could say that the inequality sign would switch, but this is only when you divide by a negative sign, so keep that in mind.

18
20
36
90

Answers

Andrew scored 36 points in two games

Answer:

Step-by-step explanation:

First we need the total number of points scored.

55+35= 90

Then we need to figure out how many points Andrew had.

2/5 of 90 points.

2/5 is .4 or 40%

So we multiply

Should teens be paid at a rate lower than the minimum wage?I appreciate the fact that some teens need to work to help support their families. But to do that, theyneed to land jobs in the first place,The bottom line is that lowering the minimum wage for teens makes it easier for them to find jobs. Anehelping all Americans find work will ultimately help improve our nation's economy.Bob Battles --General Counsel & Government Affairs Director, Association of Washington (State)BusinessNOWhy should workers get paid less simply because they happen to be teenagers? If a teen is performingthe same tasks as a 20-year-old, he or she should earn the same amount of money.Many teens have to work to help support their families. Others live on their own or are trying to savemoney for college. In recent years, the cost of higher education has skyrocketed. According to theCollege Board, average annual tuition and fees at four-year public colleges and universities have morethan doubled in the past 20 years. If teens are forced to accept lower wages, it will be even harder forthem to afford a degree. And research shows that people who graduate from college typically go on toearn higher wages.Young people aren't the only ones who would be affected by a lower teen wage. If employers find itcheaper to hire teens, older workers might get passed over for jobs.It's unfair to pay teens less than adults simply because of their age.A lot of pay inequality already exists in the U.S. For example, the Census Bureau estimates that womenearn about 82 cents for every dollar a man makes. We shouldn't pass laws that reinforce wagediscrimination especially when there's little evidence to suggest that businesses would create newjobs for teens if they could pay them less than adults.Not to mention, the U.S. economy depends heavily on consumer spending, and teens spend billions ofdollars every year.
