Question

A taxicab charges a flat rate of $5.00. They then charge $1.50 for every mile. Write an algebraic expression that gives the total cost for any number of miles. Then evaluate the expression for traveling 20 miles Think: What does it mean to

Answer 1

Explanation:

Let 'y' be the total charge for the trip and let 'x' be the number of miles.

When the number of miles x is 0, the taxicab charges $5.00, so y = 5 at first.

Then for each mile x they charge $1.50.

The algebraic expression is:

$y=1.5x+5$

To evaluate the expression for traveling 20 miles, we have to replace x for 20 in the expression above:

$y=1.5\cdot20+5=30+5=35$

Answer:

The expression:

$y=1.5x+5$

The charge for traveling 20 miles is $35
