Use only the left axis of the graph.

The left and right axes have different scales. The left axis is marked off in multiples of 20. For each year, go straight up to the solid line, then left to the left axis.

In 1940, there were about 20 televisions. In 1955, there were about 90 televisions.

Percent change: $$\frac{New-Old}{Old} * 100$$

$$\frac{90-20}{20}*100=\frac{70}{20}*100=3.5*100=350$$
