Each batch gives you 3 dozen and you need 1 1/2 cups for each batch of cookies
she uses 6 cups in total, so divide 6 by 1 1/2 to get the number of batches
6 ÷ 1 1/2 = 4 batches
so 4 batches × 3 dozen cookies = 12 dozen cookies
The graph that represents possible functions is shown in the diagram below. Point C shows the point on y-axis where f(x) and g(x) crosses. The result should be interpreted by the level of steepness of each slope
g(x) has a steeper gradient than f(x) and this indicates steeper fee rise for producing the T-shirt. So if Marissa is to choose the better value for her money to produce T-shirt, she should choose the function f(x) providing there are no other factors to consider other than prices.
