Question

Each month Liz pays $35 to her phone company just to use the phone. Each text she sends costs her an additional $0.05. In March her phone bill was $72.60. In April her phone bill was $65.85. How many texts did she send each month?

Answer 1

752&617

Explanation:

So if Liz pays $35 each month just to use the phone, we could subtract 35 from the total bill that month to get the the total cost she spent on text messages.

March:$72.60-$35=$37.60
April: $65.85-$35=$30.85

We can see that in March Liz spent $37.60 on texts in total and in April she spent $30.85 on texts in total. All we have to do is divide the amount of money she spent on texts( $37.60 & $30.85) by the cost of one text message($0.05) to get the amount of texts she sent that month.

March: $37.60/$0.05=752
April: $30.85/$0.05=617

Therefore, she sent 752 texts in March and 617 texts in April.
