Question

PLS HELP - 20 POINTS!!

Answer 1

Step-by-step explanation:

EZ = $0.15/min...eqn 1

Go = $40 + $0.05/min...eqn 2

let x be no of minutes then combine both eqns...

=> 0.15x = 40 + 0.05x...eqn 3

=> 0.1x = 40

x = 400

thus at 400mins both plans are equal

at 200mins go wit EZ...

total bill = $0.15 × 200 = $30.00

Answer 2

Answer:(a)400min

(b)EZ plan

Step-by-step explanation:

Given

For EZ plan cost $0.15 per minute

and Go Plan cost $40 + $0.05 per month

so for t minutes in a month both plan cost equals when

0.15t=40+0.05t

0.1t=40

t=400 minutes

for 400 minutes both cost equal.

(b)For 200 minutes

EZ plan cost

$200\times 0.15= 30$

GO plan costs

$40+200\times 0.05=40+10= 50$

So for 200 minutes we can use EZ plan
