With Westford Rent-a-Truck, in comparison, the family would pay $23 for the first day plus $4 per additional day. Before deciding on which company to use, Mrs. Sandoval wants to find out what number of additional days would make the two choices equivalent with regards to cost. What would the total cost be?

document.write( "With Kirk's Moving,         the cost is  25 + 2a  dollars, where \"a\" is \"additional days\".\r\n" );

document.write( "ANSWER.  One additional day.  The total EQUIVALENT cost is then  25 + 2*1 = 27 dollars = 23 + 4*1.\r\n" );
