Question

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

Answer 1

add up minutes

1stmonth+2ndmonth+3rdmonth=320+243+489=1052
how many 200's are there
6 of them (companies want money so they see, ok, you bought like 1 minute, we will charge you for the whole 200 minutes since you got in that zone)

6 times 25=150

cost is $150 (mom is not going to be happy, she spend like 3% of her waking hours takling on the phone)
