The table describes the weekly prices and quantity demanded for two goods, A and B$,$ over a three$-$week period. In the space following

the

record what type of elasticity you are calculating. Assume the price and income changes indicated in the table are

large. Round numerical answers to two decimal places, if necessary. Don't forget to include the negative sign if appropriate.

Part a$)$ Calculate the numerical value of the appropriate elasticity to determine whether Goods A and B are complements, substitutes,

or unrelated. Use $1-2$ sentences to explain how you've arrived at this conclusion.

Goods A and $B$ are

with an $E,=$

Part b$)$ Calculate the numerical value of the appropriate elasticity to determine whether Goods A and B are normal, inferior or income

inelastic $($unrelated to Income$).$ Use $1-2$ sentences to explain how you've arrived at this conclusion.

Good A is

with an $E_{-}=$

Good B is

with an $E$
