Which of the following is equal to the expression below? (160x243)^1/5

Kipish [7]

160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5
243 = 3 x 3 x 3 x 3 x 3 = 3^5
So
(160 * 243)^1/5
= 5th root of (160 * 243)
= 5th root of (2^5 * 5 * 3^5)
= 2 * 3 * (5th root of 5)
= 6 * (5th root of 5)
Answer is D. 6 * (5th root of 5)

Calculate Income Elasticity of Demand Question Suppose that when the price of cream cheese rises by 10%, the quantity of bagels

inn [45]

Answer:

eY is positive +0.1 therefore bagels are a normal good.

Step-by-step explanation:

Given data:

when, 10% rise in cheese price, 3% fall in bagels quantity observed

when, 10% rise in income, 1% fall in bagels quantity observed

from formula for cross price elasticity of demand, determine $e_{AB}$

$e_{AB} = \frac{(−3\%}{(10\%)} = −0.3.$

As, eAB is negative, bagels $ cream cheese are complements.

By formula for income elasticity of demand,

we find that $eY= \frac{(+1\%)}{(10\%)} = +0.1.$

Since eYis positive, bagels are a normal good.
