Gloria talked on her cell phone for 320 minutes the first

month, 243 minutes the second month, and 489 minutes the third month. Her payment package does not allow her to pay per minute; she can only buy groups of
minutes. If she has to pay $25 for every 200 minutes, how much did she pay
for the first 3 months?
total $175.50+50+75

That depends - do the minutes roll over, or not?

If not, then she had to buy
400 the 1st month
400 the 2nd month
600 the 3rd month

That's $50+$50+$75 = $175

If they roll over at the end of the month, then she'd have to buy less in some cases.

To find out how much Gloria paid for the first 3 months, we need to calculate the total number of minutes she talked and then determine how many groups of 200 minutes she purchased.

First, add up the minutes Gloria talked in each month:
320 minutes + 243 minutes + 489 minutes = 1052 minutes

Next, divide the total minutes by 200 minutes to find how many groups of 200 minutes Gloria needed to purchase:
1052 minutes / 200 minutes = 5.26 (rounded up to the nearest whole number)

Since she can only buy full groups of minutes, Gloria needed to purchase 6 groups of 200 minutes.

Now we can calculate how much she paid for the minutes:
6 groups * $25 per group = $150

So, Gloria paid $150 for the first three months.
