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?

Draw a dashed line to represent the graph of 5x + 10y = 1500 and shade the portion below the line for positive values of x and y.

Draw a dashed line to represent the graph of 5x + 10y = 1500 and shade the portion above the line for positive values of x and y.

Draw a dashed line to represent the graph of 10x + 5y = 1500 and shade the portion above the line for positive values of x and y.

Draw a dashed line to represent the graph of 10x – 5y = 1500 and shade the portion below the line for positive values of x and y.

Well, we know nickels are x, so 5x would accurately represent it, same with 10y for dimes. The key word in this problem, is that she knows she has LESS than $15 in her box; shade downwards. If she wanted to have more than $15 or wants more than $15, it would be upwards
