Question

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.​

Answer 1

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 )

`x = 50 - (10.50 + 8)`

`x = 50 - 18.50`

`x = 13.50`

`x = (13.50)/(4.50)`

`x = 7`

hence, Hannah rented the bike for 7 days.
