Step-by-step explanation:
From the question, Diana wants her total bill to be less than $50.
Diana pays a fixed monthly bill of
$39 for her mobile phone and an additional
$0.15 per minute for phone internet service.
The bill Diana pays for m minutes of using the internet is $0.15m in a month.
The total monthly bill becomes,

The maximum bill she wants to pay is $50.

This inequality can be solved to determine the number of available minutes.
3% as a decimal is 0.03 and I think 3% as a fraction in simplest form is 3/100
0.65/100 = x/160 Ok, until now?
You then find the cross product: (0.65)(160) = 100x
104 = 100x 104/100 = 1.04
So x = 1.04 and it is also 0.65% of 160
Hope this helps!
