Jane’s mobile phone plan charges $0.05 per minute at daytime rates before 8 p. m. and $0.03 per minute at nighttime rates after 8 p. m. A conference call costs 1.5 times the normal rate. Calculate the cost of a conference call lasting from 7 p. m. to 8:30 p. m.

Step-by-step explanation:

Cost of the conference call before 8 pm =0.15 * 0.05 = $ 0.075

Cost of the conference call after 8 pm   = 0.15 * 0.03 = $ 0. 045

Cost of the conference call from 7pm to 8pm that last  60 minutes= 0.075 * 60

= $ 4.50

Cost of the conference call 8pm to 8:30pm =0.045 * 30 = $ 1.35

Cost of the conference call 7 pm to 8:30 pm = 4.50 + 1.35 = $ 5.85

the answer is y = 11.54
