Mia’s dad has an OzMobe mobile phone plan with the following cost:

- a standard call costs 80c per minute

- sending a text to another OzMobe mobile costs 5c

-  sending a a text to any othe mobile phone costs 10c

- sending a photo costs 45c

Calculate Mia’s dad’s total mobile phone cost for January , if:

- he makes 100 standered calls

- the average length of each phone call is 2 minutes

- he sends 50 texts, of wich 15 are to OzMobe mobile phones

- he sends only two photos

Answer 1

100 standard calls @ $0.80 per call per minute=100×2×0.80=$160 for 200 minutes.

15 texts to OzMobe phones @ $0.05 per text=$0.75.

50-15=35 texts to other phones @ $0.10 per text=$3.50.

2 photos @ $0.45 per photo=$0.90.

Total bill: 160+0.75+3.50+0.90=$165.15.
