Question

Adamo saved 13 pictures oh his digital camera for a total of 12021.1kb. He deleted 32 pictures for a total of 29590.4kb If there are 108 pictures now how many kilobytes of storage did he use at the beginning

Answer 1

First solve the original number of pictures. The original number of picture is 108 + 32 – 13 which is equal to 127 pictures. Then solve the size of each picture,

12021.1 kb / 13 pic = 924.7 kb / pic

So the original storage is 127 pic ( 924.7 kb / pic) = 117,436.9 kb
