A. $4

E. $1.65
Lets assume price of Coffee in June = 100x
Price of Tea in June = 100x
Price of Coffee in July = 300x (because of 200% increase in price)
Price of Tea in July = 10x (because of 90% Decrease in price)
Price of 1.5 pound of Coffee & 1.5 pound of Tea in July will be = 450x + 15x = 465x
As per question
465x= 4.65$
x = 0.01S
So the Price of Tea in July = 10x = 10 x 0.01 = 0.1$/pound
