Accepted Answer

this problem says a parking area has a cost of $2 for the first hour and $1 for each additional hour. A fee of 50 cents is also added for taxes. If a car owner was charged 8 50 how many hours was the car parked? Let's go ahead and look at this question. It solves us cost $2 for the first hour and $1 for each additional hour and a fee of 50 cents also added for taxes and finally 8 50. So we know we have to for the first hour And one for every additional hour. So I'll say one times h. four hours And plus 0.5 for 50 cents. This total is equal to 8.5. Let's determine what our H. Is. So if we combine all of our terms here We get two plus .5 it's 2.5 plus R. One H. Is just H. And that's equal to 8.5. Now let's solve for h. 2.5 from both sides. We get h. equals six So the hours extra besides the first hour or six hours. We also have to keep in mind that we've had an additional hour to account for the $2 in the first hour. So If we say this age is six we add hour, one hour Plus the one hour for the $2. R. H. is equal to seven. And our answer is seven hours or answers. See okay I hope that we solve the problem. Thank you for watching. Goodbye
