Math for Modelers Real exam 2023…..latest update 1. Joanne sells silk-screened t-shirts at a community festival. Her Marginal cost to produce one t-shirt is $3.50. Her total cost to produce 60 t-shirts is $300, and she sells them for $7 each. Use Python to graph this information and determine the number of t-shirts Joanne must produce and sell to break even. So the equation to solve is 7x = 3.5x + 90 Solve for x to find the breakeven number of shirts: 3.5x = 90 x = 25.7 At least 26...
