Andrew has a cell phone plan that provides 300 free minutes each month for
a flat rate of $19. for any minutes over 300, andrew is charged $0.39 per
minute. which of the following piecewise functions represents charges based
on andrew's cell phone plan?

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
