Kendall has a maximum of 500 megabytes of data usage each month on her cell phone. She has used 160 megabytes this month. Each message she sends is 4 megabytes. About how many more messages can Kendall send this month? A. at least 85 messages B. at most 85 messages C. at least 165 messages D. at most 165 messages

the answer would be B you want to first subtract 160 from 500 after that you get 340 and divide it by 4 to get 85

OpenStudy (anonymous):

yeah, 500-160=340 4*85=340 AND IT WOULD BE AT MOST because is she sends more then 85 text she would be over her 500 limit
