Gloria talked on her cell phone for 320 minutes in the first month, 243 minutes in the second month, and 489 minutes in the third month. Her payment package does not allow her to pay per minute; she can only buy packages. If she has to pay $25 for each 200 minutes, how much did she pay for the first 3 months?

Gloria has the disadvantage of not being able to pay per minutes. So she has to buy packages of 200 minutes at the rate of $25. It does not matter if she is able to complete the full 200 minutes in the package, ahe has to pay the full package amount of $25.
Now Gloria during the first month talked for 320 minutes.
Then she has to buy 2 packages of 200 minutes.
The amount of money spent during the first month = (25 * 2) dollars
                                                                                   = 50 dollars
During the second month Golria talked for 243 minutes, but still she will had to buy 2 packages of 200 minutes each
Then the amount spent by Gloria during the second month = (25 * 2) dollars
                                                                                               = 50 dollars.
during the third month Gloria used 489 minutes and so she had to buy 3 packages of 200 minutes each.
Then the amount spent by Gloria during the third month = (25 * 3) dollars
                                                                                         = 75 dollars
So the total amount of money spent by Gloria during the 3 months = (50 + 50 +75) dollars
                                                                                                           = 175 dollars
So Gloria psent $175 in the first 3 months.
