Dexter Shah · Answer 1

If we assume that Jane spent $ x on the black pack

Then the cost of the book is $ 20 less that twice the cos of the black pack,

Then twice the cost of black pack is 2x, then less $ 20 we get 2x-20

Hence, 60 = 2x-20

solving for x

x = 40

Therefore, the cost of the black pack is $40.
