Properties of a equation-
Reuben rented a truck for one day. There was a base fee of $20.95, and there was an additional charge of 98 cents for each mile driven.
Reuben had to pay $302.21 when he returned the truck. Suppose the Reuben drive the truck for x miles. Thus,
[tex]20.95+0.98x=302.21[/tex]
Solve the equation to find the number of miles he drives,
[tex]0.98x=302.21-20.95\\0.98x=281.26\\x=\dfrac{281.26}{0.98}\\x=\dfrac{281.26}{0.98}\\x=287[/tex]
Thus, the number of miles did Reuben drive the truck, with the base fee of $20.95, and an additional charge of 98 cents for each mile driven is 287 miles.
