870 miles

That’s how many miles of railway China has agreed to build along the coast of Nigeria. Not for nothing, though. The two countries signed a deal worth $11.97 billion.

1.51 percent

That’s Visa’s credit card processing fee, charged to merchants with every purchase. It’s a key number in the surprise rivalry brewing between Apple Pay and mobile payment system CurrentC. The latter is backed by a consortium of retailers including Wal-Mart, Rite-Aid Target and CVS, which all shut down Apple’s system in their stores on launch day. Venture capitalist Jean-Louis Gassée breaks down both sides in his Quartz column, cutting through the PR to conclude CurrentC is all about saving merchants the card processing fee, while Apple Pay is more user-focused.

That’s how many people subscribe to the Beats Music streaming, but that could change with Apple’s recent acquisition. The Financial Times reported Apple will bundle Beats Music on all iOS devices early next year, possibly with the launch of Apple Watch. Insiders said the details are still being hammered out, but insiders told the New York Times a subscription would cost $5 to $10. The plans are likely to make Spotify sweat; as we learned during the U2 debacle, Apple has 800 million iTunes accounts.

50 states

$11.9 billion

That’s how much in outstanding student loans is currently held by Wells Fargo & Co. As the Wall Street Journal reports, the lender announced that this month, for the first time, it will lower interest rates for eligible borrowers.

That’s how much the Disney Princess line makes on merchandising in a year, which doesn’t include the mind-boggling numbers “Frozen” has made on licensing. A recent New York Times column looks at last year’s surprise mega-hit as a case study for children’s movie licensing as a whole. Turns out spending on “Frozen”-branded toothpaste, food, dresses, toys, etc. bucks trends in most other industries. This might be because one party (parents) are almost always buying for someone else (children), making the business of Elsa dresses surprisingly similar to the pharmaceutical industry.
