###### Question details

Suppose the following table describes Jocelyn’s weekly snack purchases, which vary depending on the price of a bag of chips:

 Price of bag of chips Bags of chips Containers of salsa Bags of pretzels Cans of soda $1.00 2 3 1 4$1.50 1 2 2 4

5.) What is the Cross-Price Elasticity of Demand between the quantity of salsa and the price of chips? (the sign matters here)

6.) What is the Cross-Price Elasticity of Demand between the quantity of pretzels and the price of chips? (The sign matters here. You can round to the nearest .1 decimal point.)

7.) What is the cross-price elasticity of soda with respect to the price of a bag of chips?

8.) You find that the income elasticity for a particular good is +2.5. Is this a normal or inferior good? Is it a luxury good or a necessity?

Normal Good because the income elasticity is positive

Luxury Good because the income elasticity is greater than 1 (elastic)

Inferior Good because the income elasticity is positive

Luxury Good because the income elasticity is greater than 1 (elastic)

Normal Good because the income elasticity is positive

Necessity because the income elasticity is greater than 1 (elastic)

Inferior Good because the income elasticity is positive

Necessity because the income elasticity is greater than 1 (elastic)

9.) You find that the income elasticity for a particular good is -0.5. Is this a normal or inferior good? Is it a luxury good or a necessity?

 Normal Good because the income elasticity is negative Luxuries/necessities only apply to inferior goods, so neither Inferior Good because the income elasticity is negative Luxury Good because the income elasticity is less than 1 in magnitude (inelastic) Inferior Good because the income elasticity is negative Necessity because the income elasticity is less than 1 in magnitude (inelastic) Inferior Good because the income elasticity is negative Luxuries/necessities only apply to normal goods, so neither
