Chris rented a truck for one day. There was a base fee of $14.95,, and there was an additional charge of 78 cents for each mile driven. Chris had to pay $210.73 when he returned the truck. For how many miles did he drive the truck?

Answer 1

Let's assume that Chris drove x miles.

The additional charge for driving x miles is 78x cents.

The total amount Chris had to pay is $14.95 + 78x cents.

Since 1 dollar is equal to 100 cents, we can write the total amount Chris had to pay as:

$14.95 + 78x/100.

But we know that Chris had to pay $210.73, so we can write the equation:

$14.95 + 78x/100 = $210.73.

Let's solve this equation to find the value of x.

Subtracting $14.95 from both sides of the equation first, we get:

78x/100 = $210.73 - $14.95.

Simplifying the right side of the equation, we get:

78x/100 = $195.78.

To get rid of the division by 100, we multiply both sides of the equation by 100, and we get:

78x = 19578.

Now, to find the value of x, we divide both sides of the equation by 78:

x = 19578/78.

Dividing, we get:

x = 250.

Therefore, Chris drove the truck for 250 miles. Answer: \boxed{250}.

Answer 2

wrong.

Answer 3

Apologies for the incorrect response.
Let's try again:

Let's assume that Chris drove x miles.

The additional charge for driving x miles is $0.78x.

The total amount Chris had to pay is $14.95 + $0.78x.

Since Chris had to pay $210.73, we can write the equation:

$14.95 + $0.78x = $210.73.

Let's solve this equation to find the value of x.

Subtracting $14.95 from both sides of the equation, we get:

$0.78x = $210.73 - $14.95.

Simplifying the right side of the equation, we get:

$0.78x = $195.78.

Dividing both sides of the equation by $0.78, we get:

x = $195.78 / $0.78.

Dividing, we find:

x = 250.

Therefore, Chris drove the truck for 250 miles. Answer: \boxed{250}.
