The equilibrium price is $14 and the quantity is 24.

<h3>What is the equilibrium price?</h3>

Equilibrium is the place in the market where there is no trend for change.

Buyers’ and sellers’ plans accord, and consequently quantity demanded equals quantity supplied.

The equilibrium price occurs when the quantity demanded equals the quantity supplied.

The demand and supply functions are, respectively:

Demand and supply in a market are described by the following equations: QD = 66-3p and qs = -4 + 2p.

The equilibrium price and quantity are;

QD = QS

66-3p = -4 + 2p

66 + 4 = 2p + 3p

70 = 5p

p = 70/5

p = 14

QD = 66-3p

QD = 66-3 × 14

QD = 66- 42

QD = 24

Hence, the equilibrium price is $14 and the quantity is 24.

If inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year, what would you expect to pa
tamaranim1 [39]

Answer:

$76.5

Step-by-step explanation:

We have been given that inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year. We are asked to find the price of pair of designer jeans this year.

An inflation of 2% will increase the price of pair of jeans by 2%, so price of pair of jeans this year would be $75 plus 2% of $75.

\text{Price of pair of jeans this year}=\$75+\$75\times\frac{2}{100}

\text{Price of pair of jeans this year}=\$75+\$75\times0.02

\text{Price of pair of jeans this year}=\$75+\$1.5

\text{Price of pair of jeans this year}=\$76.5

Therefore, the price of pair of jeans would be $76.5 this year.

Find the slope of the line passing through the points (-6, 6) and (4. – 7).
postnew [5]

Answer:

\displaystyle -\frac{13}{10}

Step-by-step explanation:

To solve this problem, first you have to use the slope formula of \displaystyle \frac{y_2-y_1}{x_2-x_1}.

y2= (-7)

y1=6

x2=4

x1(-6)

Solve.

\displaystyle \frac{(-7)-6}{4-(-6)}=\frac{-13}{10}=\boxed{-\frac{13}{10}}

Therefore, the correct answer is -13/10.
