The EU wants to stop a big tax from the US. This tax is 50% on things from Europe. Trump, the US leader, is not happy. He thinks Europe sells more to the US than it buys. But the EU says that if you count online things, the US sells more. To help, the EU could buy more gas from the US. They could also buy more army things from the US. Or, they could make the tax on cars from other countries smaller. But, rules about food and taxes in Europe are hard to change. Experts say this 50% tax would make Europe's money less. It could be 1% less next year. Businesses might also not spend as much money.
