A professional baseball player earned $1,715,000 from
playing baseball last year.
An autobiography he had written last year sold 300,000
copies at a price of $24 each. He received 10% in
royalties on the book sales.
What was his total salary last year?
$

Answers

Answer:

The right answer is actually $2,435,000.00

Step-by-step explanation:

The reason is because you take 300,000 and times that by 24 then you get 7,200,000 then you take that and times it by 0.10 then you get 720,000 then you add that to the 1,715,000 and you get 2,435,000.

300,000 x 24 = 7,200,000

7,200,000 x 0.10 = 720,000

720,000 + 1,715,000 = 2,435,000

So, $2,435,000.00 is your answer.

The total salary last year was $2,435,000 if a professional baseball player earned $1,715,000 from playing baseball last year.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

A professional baseball player earned $1,715,000 from playing baseball last year.

The total earning from autobiography = 300,000x24

= 7,200,000

The royalty amount = 10% of 7,200,000

The royalty amount = 0.10x7,200,000

The royalty amount = 7,200,00

Total salary last year = 1,715,000 + 7,200,00

Total salary last year = $2,435,000

Thus, the total salary last year was $2,435,000 if a professional baseball player earned $1,715,000 from playing baseball last year.

23. A man and a woman share a prize of $1000 between them in the
ratio 1:4. The woman shares her part between herself, her mother
and her daughter in the ratio 2:1:1. How much does her daughter receive?​

Answers

Number of parts = 1 + 4 = 5

Sum of all parts = $1000

Each part =

= 1000 ÷ 5

= $200

Money the man got =

= 200 × 1

= $200

Money the woman got =

= 200 × 4

= $800

The womans has $800 as her share .

Total parts = 2 + 1 + 1 = 4 parts

Sum of all parts = 800

Each part = 800 ÷ 4

Each part = 200

Then ,

The woman gets =

= 200 × 2

= $400

Her mother gets =

= 200 × 1

= $200

Her daughter gets =

= 200 × 1

= $200

∴ Her daughter receives $200 .

Answer:

Step-by-step explanation:

Simplify the following:

(7 + 1/4) 2^2 + (8 + 1/2 - 2)/3

2^2 = 4:

(7 + 1/4) 4 + (8 + 1/2 - 2)/3

Put 7 + 1/4 over the common denominator 4. 7 + 1/4 = (4×7)/4 + 1/4:

(4×7)/4 + 1/4 4 + (8 + 1/2 - 2)/3

4×7 = 28:

(28/4 + 1/4) 4 + (8 + 1/2 - 2)/3

28/4 + 1/4 = (28 + 1)/4:

(28 + 1)/4×4 + (8 + 1/2 - 2)/3

28 + 1 = 29:

29/4×4 + (8 + 1/2 - 2)/3

29/4×4 = (29×4)/4:

(29×4)/4 + (8 + 1/2 - 2)/3

(29×4)/4 = 4/4×29 = 29:

29 + (8 + 1/2 - 2)/3

Put 8 + 1/2 - 2 over the common denominator 2. 8 + 1/2 - 2 = (2×8)/2 + 1/2 + (2 (-2))/2:

29 + ((2×8)/2 + 1/2 + (2 (-2))/2)/3

2×8 = 16:

29 + (16/2 + 1/2 + (2 (-2))/2)/3

2 (-2) = -4:

29 + (16/2 + 1/2 + (-4)/2)/3

16/2 + 1/2 - 4/2 = (16 + 1 - 4)/2:

29 + ((16 + 1 - 4)/2)/3

16 + 1 = 17:

Answer: 187/6

Answer:

Step-by-step explanation:

7 1/4 × 2²+(8 1/2-2)÷3

Using PEMDAS

Parentheses first

7 1/4 × 2²+(6 1/2)÷3

Then exponents

7 1/4 × 4+(6 1/2)÷3

Changing the mixed numbers to improper fractions

7 1/4 = (4*7+1)/4 = 29/4  and ( 2*6+1)/3 = 13/2

29/4 × 4+(13/2)÷3

Multiply and divide from left to right

29 + 13/2÷3

Using copy dot flip

29 + 13/2 * 1/3

29 + 13/6

Changing back to a mixed number

13/6 = 12/6 + 1/6 = 2 1/6

29 + 2 1/6

same with the second except it is 8 and 6 times 2

Answer: A and C

Step-by-step explanation: If you take the ratio and divide both sides by 2, you get the equivalent ratio 4:3. Then if you take the ratio and multiple both sides by 2, you will get the equivalent ratio 16:12. This means that both A and C are equivalent to the ratio 8:6.

Option 1)

6a + 8s = 102

14a + 4s = 150

each adult ticket costs 9 dollars

===================================================

Explanation:

6 adult tickets and 8 student tickets bring in $102, so that means 6a+8s = 102

14 adult tickets and 4 students tickets bring in $150, so 14a+4s = 150

The system of equations is

[tex]\begin{cases}6a+8s = 102\\14a+4s = 150\end{cases}[/tex]

If we multiply both sides of the second equation by -2, we get this updated system

[tex]\begin{cases}6a+8s = 102\\-28a-8s = -300\end{cases}[/tex]

Add the equations straight down

6a+(-28a) = -22a

8s+(-8s) = 0s = 0 ... the 's' terms go away

102+(-300) = -198

So we end up with the equation -22a = -198 and that solves to a = 9 after dividing both sides by -22.

Each adult ticket costs $9

If you want the value of s, then

6a+8s = 102

6(9)+8s = 102

54 + 8s = 102

8s = 102-54

8s = 48

s = 48/8

s = 6

Meaning each student ticket costs $6

Or you could use the other equation

14a+4s = 150

14(9)+4s = 150

126+4s = 150

4s = 150-126

4s = 24

s = 24/4

s = 6

We get the same value of s
