Lisa has only nickels and dimes in her money box. She knows that she has less than $15 in the box. Let x represent the number of nickels in the box and y represent the number of dimes in the box. Which of the following statements best describes the steps to graph the solution to the inequality in x and y? a
Draw a dashed line to represent the graph of 0.05x + 0.10y < 15, and shade the portion below the line for positive values of x and y.

b
Draw a dashed line to represent the graph of 0.05x + 0.10y < 15, and shade the portion above the line for positive values of x and y.

c
Draw a dashed line to represent the graph of 0.10x + 0.05y < 15, and shade the portion above the line for positive values of x and y.

d
Draw a dashed line to represent the graph of 0.10x − 0.05y < 15, and shade the portion below the line for positive values of x and y.
