One good thing is that I don’t have to pay it back until I get a job and I’m earning5 a reasonable amount6 of money. At the moment I’m saving up7 for a new laptop; the one I have is very slow and keeps going wrong. I’d love to have a car as well, but I can’t afford8 it. ”

Language help
We use rent when we pay to use something for a long period of time, e.g. rent a flat. The noun rent is the amount you pay, e.g. The rent is £400 per month. We use hire when we pay to use something for a short period of time, e.g. I hired a bike for the day. Both verbs are used with cars, e.g. We rented/hired a car when we were on holiday.
