Question

Bella's cell phone costs $ 18 per month plus $ 0.15 for every minute she use the phone. Last month her bill was $ 29.25. For how many minutes did she use her phone last month?

Answer 1

Same- the answer is 75 minutes

Answer 2

I think it's 75 minutes because you have to subtract 29.25 from $18 then divide 0.15 by 11.25 because 29.25-1= 11.25
