Problema Solution

One half of the storage capacity of a music CD has been used. Suppose you add some songs which took 1⁄4 of the remaining capacity. If the CD can store up to 700mb, how many mb in total has been used?

Answer provided by our tutors

Total Storage = 700 mb

Half Storage = 700/2

Half Storage = 350 mb

Remaining Capacity = 700 - 350

Remaining Capacity = 350 mb

(1/4) of Remaining Capacity = (1/4)350 mb

350 + (1/4)350 = 437.5 mb

437.5 mb in total is used.
