Question 7 • AZ-Algebra 1A (MA101)
Ezra works two summer jobs to save for a laptop that costs at least $1100. He charges $15/hr to mow lawns and $10/hr to walk dogs. Recall the inequality that represents this situation: Explain how to graph the solution set.
Answer
Answer:
Graph the solid boundary line 15x + 10y = 1100 through (1100/15, 0) and (0, 110). Shade the region on or above the line in the first quadrant, where 15x + 10y ≥ 1100.
