1.Use chain rule to defferentiatey=(6x+2)^6

(Typing Hint:If your answer isy=1000(20x+1)^40, fill the blank spacewith only theright-handpartand it should be typed in small letters( lower case) as1000 (20x+10)^40

1.The demand for a commodity A is q1=15x^23y, where x andy are the prices ofcommodities A and Brespectively. Find the partial elasticities when x=3 andy=1.

Note: Round off your answers to 3 decimal places

SinceA is q1=15x^23y,it follows that

q1x=

q1y=

Thus, at x=3 andy=1
