4y = -23 + 39
4y = 16
y = 4
Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9
x = -9
y = 4
Change in value= new price-original price
Change in value=850-10000
Change in value= -9150
%decreased=change in value/original price x 100
%decreased= 9150/10000x100
The answer is 91.5%
Answer:
Step-by-step explanation:
The demand function is expressed as
D(p )=1150-50p
The supply function is expressed as S(p)=−200 + 40p
Where
p represents the price
A) The equilibrium price is the price at which the quantity supplied and the quantity demanded would be equal. Therefore
1150 - 50p = - 200 + 40p
40p + 50p = 1150 + 200
90p = 1350
p = 1350/90
p = 15
The equilibrium price is $15
b) For quantity demanded to be greater than quantity supplied, the price would be
1150 - 50p > - 200 + 40p
40p + 50p > 1150 + 200
90p > 1350
p > 1350/90
p > 15
The price would be greater than 15
c) if the quantity demanded is greater than the quantity supplied, the prices of the T shirt would increase.
The soda makes up 2/7 of the recipe. 2/7 of 56 is 16
Answer:
a = 12
Step-by-step explanation:
add 2 to each side
5a/3 = a/4 + 17
distribute 12 to remove fractions
20a = 3a + 204
17a = 204
a = 12
