Ruben rented a truck for one day. There was a base fee of $14.75 and there was an additional charge of $0.06 cents for each mile
1 answer:
Given:
The base fee is, <em>b</em> = $14.75.
The charge per mile is, <em>p</em> = $0.06.
The equation for total rent is,
The objective is to find the total rental cost for 40 miles,
Explanation:
In the given equation <em>x</em> represents the miles travelled by the person.
To find the total cost 40 miles, substitute <em>x</em> = 40 in the given equation,
On further solving the above equation,
Hence, the total rental cost for 40 miles is 17.15 dollars.
