Assume that quantities do not need to be integers. That is, it is possible for Prof. G. to purchase 37.5 lattes. (And if the price of a latte is $4, he would spend 37.5 * $4 = $150 on lattes.) Prof. G. spends all of his money on lattes and babkas and never has money left over. (Caffeine, butter and a bit of sugar. What more could you want?) Next month, he is planning on purchasing 60 lattes at a price of $4 each and 121 babkas at a price of $2 each. What is the cost, in babkas, if he increases his latte purchases to 61? Enter a number (and only a number, no units) rounded to two decimal places. If your answer is 1.275, enter 1.28.
