10th ed. OG

On page 76 PS problem #12, can someone explain the answer 3T + (4T+1). I don't understand were the 4t+1 comes from? The other text and video don't show how the book arrived at this answer, thanks.

Please post the question in its entirety.
Most of us don't have an OG10 kicking around :-)

Cheers,

It's probably also a good idea to get a new version: the test is so different now that OG 10 won't prepare you as well as it once did. You WILL be introduced to a lot of the fundamental ideas that recur on the test, but you WON'T see most of the new topics of emphasis, and you'll get so much less value for time.
