F represents the fee (in dollars) for climbing d meters.

Grace [21]

Answer:

$12

Step-by-step explanation:

when d = 0, F = 110

when d = 100, F = 110 + (0.12 x 100) = 122

when d = 200, F = 110 + (0.12 x 200) = 134

etc.

Therefore, increase in price for every 100 meters climbed = 134 - 122 = 122 - 110 = 12
