A) $50
B) $70
C) 0
D) $120

Answer 1

D

Step-by-step explanation:

The first 1000 minutes cost per month $50 and if you use 1200, minimum you will be charged with $50. To find the cost of the 200 reamining minutes, you multiply 200 times $0,35, which is the cost of one minute when you exceed 1000 minutes. Then you have:

$50⇒ for 1000 minutes

$70⇒ for 200 minutes

Total

$120⇒ for 1200 minutes
