Ответ:
Company X, about 29 minutes.
Step-by-step explanation: Well, if she is going to spend $52, then you will want to immediately subtract 5 from both companies. Then, you will need to make a function. For Company X, it will be y=.08x+.37 (with y being total dollars and x being number of minutes), for Company Y, it will be y=.14x+.52. Then you will need to substitute 52 in for y and solve both equations.

67X10^5-2.3X10^5
64.7X10^5 which can be expressed as:
6.47X10^6
(not sure if it matters to you or not, but technically we only had two significant figures so it should be rounded to 6.5X10^6)
