3. Indifference curves and utility maximization city. Making one grayscale brochure costs \( \$ 0.05 \), but adding color increases the cost to \( \$ 0.20 \) per brochure. Sharon sets aside a monthly budget \( \$ 40.00 \) for creating brochures. The following graph shows three of Sharon's indifference curves for the number of grayscale and color brochures that she makes. Use the green line (triangle symbol) to plot Sharon's budget constraint. Then, place the black point (plus symbol) on the graph to indicate Sharon's optimal consumption choice given that budget constraint. At the optimum that you indicated on the graph, Sharon's marginal rate of substitution is equal to in grayscale per brochure in color.
