Answer:

Part 1

Total cost of Plan A = $85 (plan A offers unlimited talks and message at the cost of $85)

Total cost of plan B = (cost per minute * usage minutes)+(cost per message * usage texts) = (0.20*1750)+(0.10*1600) = $510

Part 2

Total cost of Plan A = $85 (plan A offers unlimited talks and message at the cost of $85)

Total cost of plan B = (cost per minute * usage minutes)+(cost per message * usage texts) = (0.20*3500)+(0.10*3200) = $1020

The cost of plan A is fixed in nature. It does not change with number of call minutes and text messages. While the cost of plan B is variable in nature and it changes with number of call minutes and text messages.

Answer:

1) Total cost under current usage:

Plan A = $85 per month

Plan B = $510 per month (Talk 1,750 minutes at $0.20 plus 1,600 texts at $0.10)

2) Total cost with doubled usage:

Plan A = $85 per month

Plan B = $510 x 2 = $1,020

Explanation:

Plan A is actually the best option under the current and doubled usages.

Plan B is costlier than Plan A under the current and doubled usages.

I would, therefore, consider Plan A all other things being equal.
