Mr. Garcia orders luminary bags, which are small paper lanterns, to decorate his sidewalk for a holiday celebration. The graph shows the relationship between the number of luminary bags ordered and the total cost. Which equation represents the total cost, y, of x luminary bags?

Question

y = x + 2

y = 2x

y = x + 0.50

y = 0.50x

Answer 1

The equation that represents the total cost, y, of x luminary bags is:

y = 0.50x

This is because the cost of each luminary bag is $0.50, so the total cost is the number of bags multiplied by $0.50.
