Nathan sells posters. He starts with $1,000 and buys 9 posters for $28 each. He sells 5 posters for $42 each. He says that he ha

s about $900 after selling the 5 posters. Is Nathan’s estimate reasonable? Nathan’s estimate is reasonable. He spent about $200 and earned about $100 so he should have about $100 less than he started with. Nathan’s estimate is reasonable. He spent about $300 and earned about $200 so he should have about $100 less than he started with. Nathan’s estimate is not reasonable. He spent about $200 and earned about $200 so he should have the same amount of money as he started with. Nathan’s estimate is not reasonable. He spent about $300 and earned about $200 so he should have about $100 more than he started with

Answer:

Nathan’s estimate is reasonable. He spent about $300 and earned about $200 so he should have about $100 less than he started with.

Step-by-step explanation:

Lets use round #s

He buys 10 posters at $30 each, so he spent 10*30 = 300

He sells 5 posters at $40 each, so he made 5*40 = 200

So he made 200 - 300 = -100, meaning he made 100 less than he started with. 100 less from 1000 is $900.

A group of retailers will buy 104 televisions from a wholesaler if the price is $300 and 144 if the price is $250. The wholesale
stepladder [879]

Answer:

The required equilibrium point is (356.538,58.769)

Step-by-step explanation:

The two points on your demand equation are : (300,104) and (250,144)

Take the number of televisions on y-axis and the price of the television on x-axis

Now, to find the demand equation for the given problem, find slope using the above two points :

\implies Slope=\frac{144-104}{250-300}\\\\\implies Slope = -\frac{4}{5}=-0.8

And the y - intercept is : y = -0.8x + b

Find the value of b using any point. Let us take (250,144)

144 = -0.8 × 250 + b

⇒ b = 144 + 200

⇒ b = 344

So, the y-intercept is : y = -0.8x + 344

The two points on your supply equation are : (225,88) and (315,68)

Take the number of televisions on y-axis and the price of the television on x-axis

Now, to find the supply equation for the given problem, find slope using the above two points :

\implies Slope=\frac{68-88}{315-225}\\\\\implies Slope = -\frac{2}{9}

And the y - intercept is :

y = -\frac{2}{9}x + b

Find the value of b using any point. Let us take (225,88)

88 = -\frac{2}{9}\times 225 + b\\\\\implies b = 88 + 50\\\\\implies b = 138

So, the y-intercept is :

y = -\frac{2}{9}x + 138

To find the equilibrium point, solve both the y-intercepts of the demand equation and the supply equation :

⇒ x = 356.538 and y = 58.769

Hence, the required equilibrium point is (356.538,58.769)
