Simba travel agency arranges trips for climbing mount kilimanjaro. for each trip they charge an initial fee of $100 in addition to a constant fee each vertical meter climbed. for instance, the price for climbing to the shira volcanic cone, which is 3000 meters above the base of the mountain is $400. let f represent the fee (in dollars) of the trip where they climbed d vertical meters

Step-by-step explanation:

it takes  $400 to travel 3000 meterstake out the $ 100 initial fee...so it actually takes $ 300 for just the climbso it takes $ 300 for 3000 metersthen thats 300/3000 = $ 0.10 per meter

so ur equation would be :

F = 100 + 0.10d

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
