Kile is choosing between two international phone plans for his upcoming business trip. Plan A costs $40 for unlimited calls and texts plus $10 per day for data. Plan B costs $26 for unlimited calls and texts plus $12 per day for data. When will Plan A result in a better deal than Plan B?

Question

A.Plan A will result in a better deal for Kile if he goes on his trip for less than seven days.

B.Plan A will result in a better deal for Kile if he goes on his trip for more than seven days.

C.Plan A will result in a better deal for Kile if he goes on his trip for exactly seven days.

D.Plan A will never be a better deal than Plan B.

Answer 1

So, first let's calculate a week's (7 days) cost for both plans.
Plan A: $40 + $70 ($10 x 7 days) = $110
So plan A is 110 dollars. Let's see plan B:
Plan B: $26 + $84 ($12 x 7 days) = $110
So for 7 days, both plans are the same. So, the answer is D.
