Question

a parking garage charges $2 for the first hour and $1 for each additional hour. Fran has $7.50 to spend for parking. what is the greatest number of hours Fran can park?

Answer 1

2 + H = 7.50 ( H is the # of hours after the 1st hour)

2 + H = 7.50

(-2 from both sides)

——————-

H = 5.50

5.50 plus the first hour equals 6.5 hours

He can park there for 6 and a half hours

Answer 2

Find the number of greatest hour did Fran used for parking in where:
=> parking charge $2 for the first hour
=> and $1 for the additional hours.
=> Fran spent $7.5 in all.
To get the answer let’s have the solution this way.
=> 7.5 dollars – 2 dollars = we need to subtract the first hour which is 2 dollars.
=> 5.5 dollars left.
=> 5.5 dollars / 1 dollar per hour
=> 5.5 hour + 1 hour
=> 6.5 hours
Thus, Fran parked for 6.5 hours and payed 7.5 dollars.
