cell phone plan a costs $70 per month and comes with a free $500 phone. cell phone plan b costs $50 per month but does not comes with a phone. if you buy the $500 phone and choose plan b how many months is it until your cost is the same as plan a's

P is greater by 94.

Step-by-step explanation:

P =                   8 + 10 + 12 + + 102 + 104 + 106

Q= 2 + 4 + 6 + 8 + 10 + 12 + + 102 + 104

The terms from 8 + 10 + ... + 104 are the same on both P and Q.

Therefore, the different terms are the 106 in P and the 2 + 4 + 6 in Q.

Clearly 106 > 2 + 4 + 6, so P is greater.

To know by how much we would subtract 2 + 4 + 6 = 12 from 106.

106 - 12 = 94.
