From bitcoin's big day, to an aerial falling out, this is the Week in Numbers.

$30 in bitcoin is how much every citizen of El Salvador was offered this week. That as the country became the first to make the e-currency legal tender. The move sparked a tumble in bitcoin's value, and drew protests from those who think it's all too risky. But at least some Salvadorans were ready to give it a go:

"I've been using bitcoin for four years. I have had an increase in value. I can't say that I have had losses because when there's an increase in value I withdraw my money."

10.9 million was the record number of U.S. job openings in July. Economists say it points to a very tight labor market, with firms struggling to find the right person. A lingering reluctance to go back to the office may be one reason for the shortage of workers.

€60 billion, or about $71 billion, may be the new level of monthly stimulus from the ECB. Bank chief Christine Lagarde said on Thursday that she was set to trim economic support amid signs of a recovery. She wouldn't put a figure on the new spending, but Reuters sources say €60-70 billion is the plan.

$2 billion is the financial hit taken by Ford as it pulls out of India. The U.S. giant has made cars there for 25 years, but has won little market share, and now sees no road to profitability. It follows General Motors and Harley Davidson through the exit door.

And up to 10 years is how long Ryanair says it's ready to wait before placing another major order with Boeing. The planemaker seems to have fallen out with Europe's biggest budget airline over prices. Ryanair boss Michael O'Leary says he'll just wait for the next big global crisis to force Boeing into better deals.
