Sally has recently changed her mobile phone contract to another provider.
Sally’s new phone company charges 20p for each minute that she spends making phone calls.
During the first 6 weeks sally spends 1 hour and 45 minutes making phone calls.
Work out how much Sally will need to pay for the phone calls during the first 6 weeks.
Answer:
1 and ¾ hours = 105 minutes as 60 x 1.75 = 105
So to find the cost you must do 105 x 20p = 2100p
Converted to pounds this would be 2100p/100 = £21
