Answer:

The number is 4000

Step-by-step explanation:

2.5% of a number. This means:

[tex]0.025*x[/tex]

We know that this expression must be equal to 100 then:

[tex]0.025x=100[/tex]

Now we solve the equation for the variable x

[tex]0.025x=100[/tex]

Divide both sides of the equation by 0.025

[tex]\frac{0.025}{0.025}x=\frac{100}{0.025}[/tex]

[tex]x=\frac{100}{0.025}[/tex]

[tex]x=4000[/tex]
