During her holiday, Hannah rents a bike. She pays a fixed cost of $8 and then a cost of $4.50 per day.
Hannah pays with a $50 note and receives $10.50 change.
Calculate for how many days Hannah rents the bike.​

Respuesta :

given:

fixed cost= $8

cost= $4.50

payed= $50

recieved= $10.50

to find:

how many days Hannah rented the bike.

solution:

let the unknown be ( x )

[tex]x = 50 - (10.50 + 8)[/tex]

[tex]x = 50 - 18.50[/tex]

[tex]x = 13.50[/tex]

[tex]x = \frac{13.50}{4.50} [/tex]

[tex]x = 7[/tex]

hence, Hannah rented the bike for 7 days.
