Grayson is ordering a taxi from an online taxi service. He has to pay a flat charge just
to order the taxi, and then has to pay per mile, depending on how far he travels. He
wrote an equation to represent his total cost, y = 2.9x + 4.5, where y represents
the total cost in dollars and cents, and x represents the number of miles he travels.
What could the number 2.9 represent in the equation?
2.9 the rate per mile he has to pay. it gives him the cost of the travel after a specific distance. this is excluding the the flat charge of 4.5 he has to pay.
