Sarah operated her lemonade stand Monday through Friday over a two week period and made a total profit of 350 dollars. On hot days she sold cups of lemonade for a price that was 25 percent higher than the regular days. Each cup she sold had a total cost of 75 cents and Sarah did not incur any other costs. If every day she sold exactly 32 cups and 4 of the days were hot, then what was the price of 1 cup on a hot day? Pick one:
A) $ 1.50
B) $ 1.88
C) $ 2.09
D) $ 2.50
E) $ 3.25
6 regular days --&gt; sales = 6*32*x = 192x;   4 hot days --&gt; sales = 4*32*(1.25x) = 160x;   Total sales 4*32*(1.25 )=

160x;   Total sales= 192x+160x = 352x.   Total cost 192 +160=

352x.   Total cost= 10*32*0.75=
