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?

Thus, Fran parked for 6.5 hours and payed 7.5 dollars.

Step-by-step explanation:

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.

the answer

b. they are parallel and will never intersect.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
