Ellie took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.50 plus $5 per mile. The total fare was $76.50, not including the tip. Write and solve an equation which can be used to determine mm, the number of miles in the taxi ride.

15 miles

Step-by-step explanation:

5 = price per mile   x= number of miles   1.5 = pick-up fee   76.5 = total  

5x + 1.5 = 76.5

5x = 76.5 - 1.5

5x = 75

x =75/ 5

x = 15

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
