Gloria talked on her cell phone for 320 minutes in the first month, 243 minutes in the second month, and 489 minutes in the thir
d 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.
B)The rate of change is constant because for every 5 seconds the change is the same. For every 5 seconds, the height decreases by 60ft. The equation is y=12x+1210
