Revised my rough draft,could you check and see if it's better.Thank you. For the past three months, I have noticed problems in the work flow within our company, DMD Medical Supplies. The problems are with my two employees, Jack Snyder and Ruth Disselkoen....

The year was 2003

Why would Aops need answers...

a + 5d = 37 ... Eqn 1 6a + 15d = 147 ... Eqn 2 Solve eqn. 1 and 2 simultaneously a = 12 d = 5 First term = 12 S(15) = 15/2[2a + 14d] S(15) = 15/2[(2x12) + (14x5)] S(15) = 705 sum of the first fifteen terms is 705

idk how to solve that so telling us the answer would be helpful
