The answer is 5 I have shown my work in the picture
Answer:
P': (0,-2) S: (0,-7) Q: (-5,-3) R:(-8,-7)
Step-by-step explanation:
Tires:
65(2) - 45(2) = 130 - 90 = $40 profit
Rims:
126(3) - 85(3) = 378 - 255 = $123 profit
Headlights:
15(5) - 5(5) = 75 - 25 = $50 profit
Total profit:
$40 + $123 + $50 = $213 profit
