Answer:
Step-by-step explanation:
1.
Let the indifference point in miles be M
Savings for the guarantee = Savings for the discount
[$4.98 x (M/15)] — [$2.90 x (M/15)] = $4,700
$4.98M - $2.90M = $70,500
M = $70,500/2.08
M = 33,894 miles over three years
Or 11,298 miles (33,894/3) per year
Therefore, the indifference point in miles is33,894 over the three years period or 11,298 miles per year
2 Miles driven over 3 years = 9,750 miles X 3 = 29,250 miles
Let the indifference point in gasoline be G:
[G x (29,250/15)] - $4,700 = $2.90 x (29,250/15)
G (29,250/15) = $10,355
G= $5.31 average gas price for the next three years
