\hbox{the sum identity:} \\ \sin(\alpha + \beta)= \sin \alpha \cos \beta + \sin \beta \cos \alpha \\ \\
\sin (90^\circ +q)= \\ \sin 90^\circ \cos q+ \sin q \cos 90^\circ= \\
1 \times \cos q + \sin q \times 0= \\

Suppose that a consumer's preferences are well behaved in that properties 4-1 to 4-4 are satisfied and the initial equilibrium c
scoray [572]

Answer:

Normal goods

Step-by-step explanation:

Initial consumption bundle: X = 10 units and Y = 25 units

After the price of Y rises

So,

The new Consumption bundle is

X = 15, Y = 10

Hence, Good X and Y are normal goods .

As the price of good Y increases, the consumption of good Y decreases from 25 to 15 units as the actual revenue decreases, so the consumption decreases

Although the price of good X stays the same but is now comparatively lower, demand increases mean that consumption increases as real revenue increases.

This indicates that the sales impact is positive, implying that good X and Y are ordinary items.

marshall27 [118]
In this problem the question asked is what principal should be invested on a rate of interest of 3.6% for 10 years to get the totals amount as 50000$
the formula for compound interest is
A=P*(1+R/100)^T
we shall replace the formula
50000=X*(1+3.6/100)^10
50000=x*(100/100+3.6/100)^10
50000=x*(103.6/100)^10
50000=X*(1.036)^10
50000=1.4242x
50000/1.4242=X
35107.42=X
hope u found this useful
