Answer
$37,500
Step-by-step explanation:
1) F =$2.25 +$0.20(m-1) and F=6.05 gives 6.05 = $2.25 +$0.20m - $0.20 => $0.20m = 6.05-2.25+0.20 => $0.20m = 4 => m = 20 Jaun's travel 20 miles. 2) F =$2.25 +$0.20(m-1) and F=7.65 gives 7.65 = $2.25 +$0.20m - $0.20 => $0.20m = 7.65-2.25+0.20 => $0.20m = 5.6 => m = 28 Jaun's travel 28 miles. 3) D= 0.8V - 0.08Vy and D = 9600, V =20,000 gives 9600 = 0.8*20000 - 0.08*20000* y = > y = 4. The car is 4 years old. 4) D= 0.8V - 0.08Vy and D =12000, y = 6 gives 12000 = 0.8 V - 0.08*V*6 => 12000 = 0.32V = > V = 37,500.
