For each order, a mail order bookseller charges a fixed processing fee and an additional shipping fee for each book in the order. 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 fees for these 5 orders?
1.) Rajeev’s processing and shipping fees were $1 more for his order in March than for this order in January.
2.) The total of Rajeev’s shipping fees for the five orders was $7.50.

From Question:
Jan: P+S
Feb: P+2S
Mar: P+3S
Apr: P+4S
May: P+5S
P= Processinf Fee
S = Additional Shipping per book
(1) P+3S = P+S+1
S = 1/2
No information given about processing fees therefore can't figure out the total (can only figure out shipping fees)
(2) S+2S+3S+4S+5S = 7.50
15S = $7.50
S = 1/2 (note: consisten with (1))
No information given about processing fees therefore can't figure out the total (can only figure out shipping fees)
Taking the two together there is still no information about processing fees therefore we can't figure out the total.
