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.
