Explanation Given Information: Mack’s parking Garage charges $4.00 for the first hour and $2.50 for each additional hour and if he replies “between 14 and 24 dollars”. Calculation: Suppose the number of hours is 4. The number of hours is 4 and charges for the first hour is $4.00 and $2.50 for each additional hour and the parking charge is between 14 and 24 hours. 14 < 4 + 2.50 ( 4 − 1 ) < 24 14 < 4 + 2.50 ( 3 ) < 24 14 < 4 + 7.5 < 24 14 < 11.5 < 24 This shows that the charge is cannot between 14 and 24 hours. It means guess is incorrect. Now, translate the problem: Let x be the number of hours. It can be reworded that Mack’s parking Garage charges $4.00 for the first hour and $2.50 for each additional hour and the parking charge is between 14 and 24 hours. Translate the problem into inequality as 14 < 4 + 2.50 ( x − 1 ) < 24 . Solve 14 < 4 + 2.50 ( x − 1 ) < 24 . 14 < 4 + 2.50 ( x − 1 ) < 24 14 − 4 < 2.50 ( x − 1 ) < 24 − 4 10 < 2
