A clothing business finds there is a linear relationship between the number of shirts, n ,it can sell and the price, p , it can charge per shirt. In particular, historical data shows that 1000 shirts can be sold at a price of $66, while 10000 shirts can be sold at a price of $48. Give a linear equation in the form p
Answer: p = [tex]\frac{-n}{500} +68[/tex]
Step-by-step explanation:
Let n represent the number of shirts and p represent the price, the there is a linear relationship between n and p, then the model equation is given as:
p = mn + b, where
m = slope and b is the intercept
From the question, when n = 1000, p = $66
And, when n = 10,000 , p = $48
The formula for finding slope is given as:
m = [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
[tex]y_{1} = 66[/tex]
[tex]y_{2} = 48[/tex]
[tex]x_{1} = 1000[/tex]
[tex]x_{2} = 10000[/tex]
substituting the values,
m = [tex]\frac{48-66}{10000-1000}[/tex]
m = [tex]\frac{-18}{9000}[/tex]
m = [tex]\frac{-2}{1000}[/tex]
m = [tex]\frac{-1}{500}[/tex]
The linear equation thus becomes
p = [tex]\frac{-n}{500}+b[/tex]
To find the value of b, substitute p = 66 and n =1000 into the equation
That is,
66 = [tex]\frac{-1000}{500}+b[/tex]
66 = -2 + b
68 = b
Therefore b = 68
The linear equation is therefore
p = [tex]\frac{-n}{500} +68[/tex]

Write the missing exponent that makes the equation true: 4^t times 2^t = 2^what
4^t × 2^t = 2^what [convert all terms to the same base (2)]
∴ 2^t × 2^t × 2^t = 2^what [use the multiplicat law of exponents]
2^(t+t+t) = 2^what [simplify]
2^3t = 2^what
what = 3t

I NEED SOMEONE WHO IS GOOD AT MATH AND WHO CAN GIVE ME THE RIGHT ANSWERS FOR THESE ASAP NO LINKS !!!
Step-by-step explanation:
2x + 9 = 35
→ 2x = 35 - 9 = 26
→ x = 26/2 = 13
→ x = 13
therefore, option A is correct
4 + | 7 - m | = 5
→ | -m + 7 | = 5 - 4
→ - m + 7 = 1 ( however or (only) m < 7 )
→ ( -m + 7 ) ( however or only m ≥ 7 )
→ m = 6 and m = 8
therefore, Option B is correct.
3t + 3/5 = 6
→ 3t + 3 = 6 × 5 = 30
→ 3t = 30 - 3 = 27
→ t = 27/3 = 9
→ t = 9
6(d + 1) - 2d = 54
→ 6d + 6 - 2d = 54
→ 4d + 6 = 54
→ 4d = 54 - 6 = 48
→ d = 48/4 = 12
→ d = 12
-110 = 13 + 3(4h - 6)
→ -110 = 13 + 12h - 18
→ -12h = 13 - 18 + 110
→ -12h = 105
→ h = 105/12
→ h = 8.75
hope this answer helps you dear!..

A girl can run 6 2/3 metres in one second. How long will it take her to run 100 metres?
HELP PLEASE.
Answer:
15 seconds
Step-by-step explanation:
How did i get this answer? It is apparent that the girl is capable of running 6 2/3 metres per one second and she must run 100 metres.
First, let's convert 2/3 into a decimal so that it is easier to calculate later. 2/3=0.667 (you can also just do 2 divide by 3 and will end up with the same number)
Now our numbers are 6.667 and 100. Let's divide 100 by 6.667 which estimates to 15
Answer:
It will take the girl 15 seconds to run 100 meters
Step-by-step explanation:
100÷6 2/3 is 15
reverse it to see if your right: 15×6 2/3 is 100

the rate of change of this function in miles per week?
A) 1
B) 3
C) 6
D) 10
The rate of change of this function in miles per week is 3 miles per week.
What is a expression? What is a mathematical equation?Linear function is a function whose degree is one. It is of the form -f(x) = ax + bA mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have a table as shown in the question.
The rate of change in miles per week is -
(19 - 13)/(3 - 1) = (22 - 19)/(4 - 3)
6/2 = 3/1
3 = 3
3
Therefore, the rate of change of this function in miles per week is 3 miles per week.
