The supply and demand for a product are related to price by the following equations, where y is the price, in dollars, and x is the number of units, in thousands. find the equilibrium point for this product. y=300+50x y = 13800-40x
the equilibrium point is (150,7800).

Equilibrium Price = $7800

Explanation:

Given that,

y = 300 + 50x

y = 13800 - 40x

where,

y represents the price in dollars and x represents the number of units

Equilibrium point is where both the equations are equal,

300+50x = 13800-40x

90x = 13500

x =

x = 150 units

y = 300 + 50 × 150

y = $7800

(x,y) = (150, 7800)

Therefore,

Equilibrium Price = $7800

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
