Sahara is selling cups of lemonade as a fundraiser. she records the grams of lemon powder used to make a batch of lemonade, y, and the time, x, it takes to sell the lemonade in hours. her data set is: (0,0.05),(1,0.1),(2,0.2),(3,0.4),(4,0.8) and (5,1.6). if it took seven hours to sell the lemonade, how many grams of lemon powder did she use?

we know that 2+2=5, because we can take the 2 and turn it into 2 ones, and do the same to the other two. we can then use our counting skills and add the  ones to each other. we know we have five fingers, (but everyone knows the thumb is not a finger) and when we add all of these ones together on our fingers, all of our fingers are lifted, (except for the thumb but that is not a finger as everyone knows) so we know that 2+2=5
