I think the answer would be d(greater than or equal to) -28
Step-by-step explanation:
it so easy bro 5.5 ok bro.
Part A: c for cost. c=0.31m+0.5
0.31m is the cost per minute. 0.5 is cost per call.
Part B: 0.31m+0.5=5.15 to solve we must rearrange.
subtract 0.5 from each side giving us 0.31m=4.85
divide by 0.31 giving us m=15.65
64 inches is the correct answer. To get it you need to multiply the length times the width.
(this is incorrect. Sorry for the inconvenience)
