Rajeev placed five different orders with this bookseller - an order for 1 book in January, an order for 2 books in February, an order for 3 books in March, an order for 4 books in April, and an order for 5 books in May. What was the total of Rajeev's processing and shipping fee for these five orders?

(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: 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"
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?

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)
