Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.

On any given week, if Salesman B earns $1,020, how many sales did he have for the week?
______ sales

Answers

If we take the paycheck amount of $1020 and subtract it by the weekly salary of $300.

$1020 - $300 = $720

We get $720 in sale commissions. So to get the number of sales, you divide the $720 by the $40 per sale commission.

$720/$40 = 18

Therefore, the sales Salesman B has for the week is 18.

1,020 - 300 = 720
720/40 = 18
So hear is the answer = $18 ok bye hope helps

i need help with prob #2 on this

Answers

Answer:

x and y are not in direct variation.

Step-by-step explanation:

Direct Variation

Two variables x and y have a direct proportion or variation if:

y = k.x

Where k is the factor of proportionality. The value of k must be constant for every ordered pair (x,y). If only one of them does not have the very same k, then the relationship is not direct.

The value of k can be solved from the equation:

[tex]\displastyle k=\frac{y}{x}[/tex]

Let's substitute the given points in the table:

(2,8)

[tex]\displastyle k=\frac{8}{2}=4[/tex]

k = 4

(4,16)

[tex]\displastyle k=\frac{16}{4}=4[/tex]

k = 4

(6,30)

[tex]\displastyle k=\frac{30}{6}=5[/tex]

k = 5

Since the value of k is not constant, then x and y are not in direct variation.

Answers

Answer:

12/15 and 16/20

Step-by-step explanation:

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

12/15 simplified is 4/5.

16/20 simplified is 4/5

I really need this, it could determine whether I fail or not.So I have this essay that's due in two days, all I want is a good rough draft of it. It's about "Public Schools vs Private Schools". I will give BRAINLIEST to the person who helped the most.I already made a rough draft to help but it isn't that good- Private School vs Public School A lot of people wonder, is private school better than public school?Most public schools are paid for by local taxes. Private schools can range from anywhere from $7,000 to $25,180 per year. This is a lot of money but because they spend more money, private schools give students more opportunities and can really benefit in the long run.I believe private schools are a better choice than public schools because private school students have better test scores, classes are more focused on the students goals, and private schools have a better diversity than public schools. A recent recap of high school graduates showed private school students scoring 3.1 points higher on the ACT test. Another comparison on math tests showed that private school students scored on average 18 points higher for eighth grade, and only 8 points higher for fourth grade. This supports my opinion because it talks about how the average private school student can score higher than a public school student which looks very good on a college application. Private school are not under state supervision, that means that private schools can offer curriculums that are more of the students focus. For students that want to study art or theater private school is more recommended. As the article states Due to ever-changing budgets and mandated testing, public schools are more focused on the core classes, often at the expense of more peripheral subjects. If a student wanted to become someone in the entertainment business then they would prefer private school because thats where they can focus more on theater production than public schools. From the article, it states that Numerous studies have shown that private schools, on the whole, offer a more positive peer environment. The students have a better understanding of the topic because they can have one on one peer help. Because the classes are smaller than the average public school classroom the students can better benefit and learn better with their peers. In conclusion, I think private school is better than public because it can offer smaller class sizes, more individual attention, and a better understanding of how each student prefers to learn.Yeah I know this is a lot, but please, I'm begging you, please help.
