--description--
Given a photo size in megabytes (MB), and hard drive capacity in gigabytes (GB), return the number of photos the hard drive can store using the following constraints:
- 1 gigabyte equals 1000 megabytes.
- Return the number of whole photos the drive can store.
--hints--
numberOfPhotos(1, 1) should return 1000.
assert.equal(numberOfPhotos(1, 1), 1000);
numberOfPhotos(2, 1) should return 500.
assert.equal(numberOfPhotos(2, 1), 500);
numberOfPhotos(4, 256) should return 64000.
assert.equal(numberOfPhotos(4, 256), 64000);
numberOfPhotos(3.5, 750) should return 214285.
assert.equal(numberOfPhotos(3.5, 750), 214285);
numberOfPhotos(3.5, 5.5) should return 1571.
assert.equal(numberOfPhotos(3.5, 5.5), 1571);
