In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

AT&T $389.99 ===> $15.00 discount

T-Mobile $400.99 ====> $10 mail-in rebate

Sprint $379.00 ===> 10% discount

Straight Talk $400 ===> 20% discount

Step 02:

Cost

AT&T

389.99 - 389.99*0.15 = 331.49

T-Mobile

400.99 - 10 = 390.99

Sprint

379.00 - 379.00*0.1 = 341.1

Straight Talk

400 - 400*0.2 = 320

The answer is:

Straight Talk it is the lowest cost = $320
