Answer:
The number of people who owned computers last year was 1500.
Step-by-step explanation:
The information provided is as follows:
Let X denote the number of people who owned computer last year.
And Y denote the number of people who owned computer this year.
Then:
Y = X × (100% + 60%)
[tex]2400=X\times 1.60\\\\X=\frac{2400}{1.60}\\\\X=1500[/tex]
Thus, the number of people who owned computers last year was 1500.
