The cost per pound of green tea and coffee were the same in June. In July, the price of coffee shot up by 100% and that of green tea dropped by 70%. If in July, a mixture containing equal quantities of green tea and coffee costs $3.45 for 3lbs, how much did a pound of green tea cost in July? Choices
A) $ 4 B) $ 0.3 C) $ 1 D) $ 3 E) $ 1.65
