Introduction
7. Joining tables

Instruction

Good. The last important thing we need to test is joining tables.

Exercise

Take a look at another table we've prepared: gdp_per_capita. GDP per capita is a statistical measure of a region's economic performance. Our table has two columns: city and gdp_value.

For each city, show a single row with three columns: name of the city, usd_spent, and gdp_value.
