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]
