Respuesta :

Answer:

Option D. [tex]25\ students\ in\ cooking\ club[/tex]

Step-by-step explanation:

Let

x-----> the number of students in art club

y-----> the number of students in drama club

z-----> the number of students in cooking club

we know that

[tex]\frac{x}{y} =\frac{7}{13}[/tex]

[tex]x=\frac{7}{13}y[/tex] -----> equation A

[tex]\frac{z}{x}=\frac{5}{14}[/tex]

[tex]z=\frac{5}{14}x[/tex] -----> equation B

[tex]y=130\ students\ in\ drama\ club[/tex]

step 1

Substitute the value of y in equation A and solve for x

[tex]x=\frac{7}{13}(130)=70\ students\ in\ art\ club[/tex]

step 2

substitute the value of x in equation B and solve for z

[tex]z=\frac{5}{14}(70)=25\ students\ in\ cooking\ club[/tex]
