Question

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 ?

Answer 1

Mark used 6.43 megabytes of data.

Explanation:

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

For finding the amount of data Mark used, we need to solve the above equation for
`m`.

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

`5.25+0.3m-5.25= 7.18-5.25\\ \\ 0.3m=1.93`

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

`m=(1.93)/(0.3)=6.4333... \approx 6.43`

(Rounded to the nearest hundredth)

Thus, Mark used 6.43 megabytes of data.
