Question

The number that is 40% more than five more than a number a.

I have a total of 10 gigabytes of data on my computer, x gigabytes are movies, pictures take up half the amount of space that movies do and the rest is music. How many gigabytes of music is stored on my computer?

Answer 1

40% more means 100% + 40% = 140% = 1.4

So 40% MORe than five more than a number A:

(a+5)*1.4

Movies: x gig

pictures: x/2 gig

music: 10 - x - x/2 = 10 - (3/2)x
