QUESTION 4 Nicо hаs tо decide which оf the two cell phone pаckаges he has to use for making his work calls. He only works from Monday to Friday and has his own private phone for use after hours and during weekends. Total calls made on 25 May Length of calls in minutes and seconds Length of calls in seconds 3 minutes 29 seconds 209 seconds 0 minutes 58 seconds 58 seconds 12 minutes 3 seconds 723 seconds 8 minutes 22 seconds 502 seconds Prepaid Option 7c per second (during working hours) Contract Option R450,90 per month, which includes 200 minutes (charged per minute or part thereof). Thereafter, calls are charged at R1,37 per minute (during work hours). 4.1 Show how the answer of 209 seconds was calculated from 3 minutes 29 seconds. (2) 4.2 For how many seconds did he talk in total during the day of the 25 May? (2) 4.3 Using the prepaid option, he would pay per second. Using your answer from question 4.2 to calculate how much he would have to pay for the calls that he made on 25 May. (Express your answer in Rands.) (3) 4.4 Use 27 minutes as the average amount of minutes used per day. Calculate the total amount of minutes used in a 20 work day month. (2) 4.5 Choose which option (Option 1- Option 3) was used to calculate the contract cost for any number of minutes used. Option 1: R 450,90 + R 1,37 (minutes used – 200 minutes) Option 2: R0,07 x minutes used Option 3: R450,90 + R1,37 x minutes used (2) 4.6 Use the formula from 4.5 to calculate the price for the use of 400 minutes in a month.
