Answer:
$250
Step-by-step explanation:
The goal here is to find the cost of the painting BEFORE the 60% increase.
To find the cost of the painting, we must take in the information we already have:
Increase percent: 60%
Original price: unknown
Price after increase: $400
$400 is the price of the painting AFTER the increase has been added. So this equals the cost of the painting before the increase, plus the total amount of the increase (which is 60% of the original price).
The total must be (100% + 60% = 160%) 160% of the original painting price.
To find the original price, we must divide the increased price by the new percentage (160%). But how do we get here?
Well, we have 160% and our (fraction) $400/1%. We will have to switch the 160% and the 1%, giving us..
1% $400/160%
We take 400/160, which is 2.5. But this is only 1% of the original price! We want 100%.
So now, we multiply the 2.5 by 100 to get our answer: $250.
Demand:
price quantity q(p)
p q
1 110
2 50
linear function:
q - 110 110 - 50
---------- = --------------
p - 1 1 - 2
q - 110
----------- = - 60
p - 1
q - 110 = - 60 (p - 1)
q - 110 = -60p + 60
q = - 60p + 170
Answer: demand equation: q(p) = 170 - 60p
Supply
price quantity
p q
1 50
2 110
linear function
q - 50 110 - 50
--------- = --------------
p - 1 2 - 1
q - 50
-------- = 60
p - 1
q - 50 = 60 (p - 1)
q - 50 = 60p - 60
q = 60p - 60 + 50
q = - 10 + 60 p
Answer: supply q(p) = - 10 + 60p
Price at which there is neither a surplus nor a shortage => equilibrium price
=> demand = supply
=> 170 - 60p = -10 + 60p
=> 60p + 60p = 170 + 10
120p = 180
p = 180 / 120 = 1,50
Answer: at $ 1,50
Answer:
Around 364
Step-by-step explanation:
So to fund the answer, you need to find how much they can eat per minute: 32/5 = 6.4 (around 6 lunches)
Then you multiply this by 57: 57x6.4 = 364.8
