1) Rajeev's processing and shipping fees were $1 more for his order in March than for his order in January 2) The total of Rajeev's shipping fees for the five orders was $7.50 E. Both gives us shipping fees total pro.fee + ship fee = pf(5) + sf(15) [ (pf + sf) + (pf+ 2sf)...] 1) we can find shipping fee, insuff alone. (pf + 4sf)  (pf + 3sf) 2) sf (15) = 7.20

1) Rajeev's processing and shipping fees were $1 more for his order in March than for his order in January 2) The total of Rajeev's shipping fees for the five orders was $7.50 1: y+x+1=y+3x > 1=2x > 1/2=x Nothing about the fixed fee. 2: 15x=7.50 again x=1/2 Insuff. Together: insuff.

1) Rajeev's processing and shipping fees were $1 more for his order in March than for his order in January 2) The total of Rajeev's shipping fees for the five orders was $7.50 Statement says : "a mail order bookseller charges a fixed processing fee and an additional shipping fee for each book in the order" S = additional fee. P = processing fee. J  S + P F  S + S + P Ma  S + S + S + P A  S + S + S + S + P M  S + S + S + S + S + P total = 15S + 5P 1) 1) Rajeev's processing and shipping fees were $1 more for his order in March than for his order in January Ma  J = 1 S + S + S + P  (S + P) = 1 2S = 1 S = 1/2 2) 15S + 5P = 7.5 15*1/2 + 5P = 7.5 Sounds like processing fee is zero My answer is C. whats the OA?

OA is E. good explanation, alpha. thanks. alpha_plus_gamma wrote: E. Both gives us shipping fees

Let f be processing fee per order and x $ as shipping charge per book. So Total charge for Rajiv's order is 5f+15x (jan to may) Statement 1. Charge for Jan = f+ x Charge for March = f+ 3x Difference is 2x = 1$ x= 0.5$ Statement 2. Total shipping charge is 5x+4x+3x+2x+1x= 15x 15x=7.5$ x=0.5$ Combining both all we get is shipping charges per book. Still couldnt find f. hence ans (E)
