➷ 3x + 7 / 4x + 7 = 4/5

Cross multiply:

5(3x + 7) = 4(4x + 7)

Expand:

15x + 35 = 16x + 28

Subtract 28 from both sides:

15x + 7 = 16x

Subtract 15x from both sides:

x = 7

4(7) = 28

Dom is 28 years old

25% of what nember is 19

attashe74 [19]

You would do 0.25x (x is the unknown total number)=19. It is because of is a multiply sign, so 0.25*x=19. Divide both sides by 0.25 and you get 76 as your answer.

The demand function of blankets at COMESA is given by the equation P=60-2Q find the units of good Q ,when P=12 and use integrati

lions [1.4K]

Answer:

a. 24

b. 864

Step-by-step explanation:

a. The demand function is:

P = 60 - 2Q

When P = 12:

12 = 60 - 2Q

2Q = 60 - 12

2Q = 48

Q = 48/2 = 24

b. Consumer surplus is given as the integral of Demand function:

$CS = \int\limits {[P(Q) - (p)(Q)] \ dQ\\$

This implies that:

$CS = \int\limits {60 - 2Q} \, dQ\\\\CS = 60Q - Q^2\\\\CS = (60 * 24) - 24^2\\\\CS = 1440 - 576\\\\CS = 864$
