Answer 3

to start with, define the functions

Answer 4

what do u mean ?

Answer 5

write an equation for each plan, how much does each one cost us?

Answer 6

y=0.20x+50 ?

Answer 7

close, its a pain when they use such similar numbers

plan1: if 0 minutes are used it costs us 0, each minute used is .20

plan1 = .20 x + 0


plan2: if 0 minutes are used it costs us 50, each minute used is .02

plan2 = .02 x +5 0

Answer 8

which one costs more per minute used? regardless of the monthly fee?

Answer 9

plan 1

Answer 10
