Digital camera memory card is 1/4 full. Card is 2/3 full when 375 more pictures have been taken. How many pictures can memory card hold? How pictures were originally on memory card?

Answer 1

number of pictures it can hold --- x

(1/4)x + 375 = (2/3)x
times 12

3x + 4500 = 8x
5x = 4500
x = 900

so originally we had (1/4)900 = 225 pictures

Answer 2

485
