Question

A taxicab company charges a flat fee of $1.85 plus an additional .40 per quarter mile

Write a formula to find the total cost?

Use this formula to find the cost for 1 person to travel 8 mi

Answer 1

The "flat fee" is a constant, and 0.40 is the ratio wherein it's going to be multiplied by depending on the amount of miles driven. Use the formula: y = mx + b; where "m" is the ratio and "b" the constant.

y = 0.40x + 1.85

Answer 2

Also, note that y = f(x); and "x" can be anything.

For 8 miles, substitute "8" into f(x).

f(8) = (8)*0.40 + 1.85
f(8) = 3.2 + 1.85
f(8) = 5.05

For 8 miles, the total cost will be $5.05
