Mark signed an appointment to receive internet service on his mobile phone for the service he pays a monthly fee plus a charge for each megabyte of data used. The equation 5.25 +0.3m =7.18 can be used to determine the megabytes of data mark used during one month. How many megabytes of data, to the nearest hundredth of a megabyte, did mark use ?

Respuesta :

Answer:

Mark used 6.43 megabytes of data.

Step-by-step explanation:

The given equation is:   [tex]5.25+0.3m=7.18[/tex] , where [tex]m[/tex] is amount of data used in megabyte.

For finding the amount of data Mark used, we need to solve the above equation for [tex]m[/tex].

First subtracting 5.25 from both sides, we will get.....

[tex]5.25+0.3m-5.25= 7.18-5.25\\ \\ 0.3m=1.93[/tex]

Now, dividing both sides by 0.3 ...........

[tex] m=\frac{1.93}{0.3}=6.4333... \approx 6.43[/tex]

(Rounded to the nearest hundredth)

Thus, Mark used 6.43 megabytes of data.
