[tex]\Huge\bold\red{d.40}[/tex]
Step-by-step explanation:
The sum of a number and four times the number is 200
Let the number be x
[tex]\large\bold\blue{\tt{mathematical\: equation:}}[/tex]
[tex]x + 4x = 200[/tex]
[tex]\large\bold\blue{\tt{solution:}}[/tex]
[tex]x + 4x = 200 \\ 5x = 200 \\ \frac{5x}{5} = \frac{200}{5} \\ \red{\boxed{x = 40}}[/tex]
∴ The number is 40.
