Question

Rent-A-Tent rents party tents for a flat fee of $365 plus $125 a day. Capital Rentals rents party tents for a flat fee of $250 plus $175 a day. Delia wrote the following equation to find the number of days for which the total cost charge for the two companies would be the same:

365x+125=250x+175

Find ans explain the error in Delia's work. Then write the correct equation.

Answer 1

The reason it is wrong is because the variable is on the flat fee number ( 365 and 250). The point of the variable in this case is the amount of days someone rents a tent. Since you pay a one time fee of 365 or 250 it should not belong here instead it belongs to the 125 and 175 numbers. So the right equation is 365+125x=250+175x.

Answer 2

365+125x=250+175x

X has to be the variable to go along with the number of days not the flat rate.
