To find out how many cars Alex sold, we start with his total earnings of $1450, which includes a base salary of $400 plus an additional $150 for each car sold.
First, we subtract the base salary from his total earnings:
\[
1450 - 400 = 1050
\]
This amount, $1050, is what he earned from selling cars.
Next, we calculate the number of cars sold by dividing the earnings from car sales by the amount earned per car:
\[
\text{Number of cars sold} = \frac{1050}{150}
\]
Calculating this gives:
\[
\frac{1050}{150} = 7
\]
Thus, Alex sold **7 cars**.
