Question

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.

Answer 1

there is this magical thing called google

Answer 2

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. I hoped this helped.
