Every student can invite 4 of family members and  friends  .
Step-by-step explanation:
Here we have ,  Mr. Gonzalez's sixth-grade class is putting  on a play. He reserved the first 6 rows of  the auditorium for family members and  friends of the 24 students in his class.  If each row contains 17 seats and each !  student can invite the same number of  guests, We need to find that how many guests can each student . Let's find out:
Total Number of family members and  friends of the 24 students is :
⇒ [tex](Number-of rows)(Number-of-seat-in-a-row)[/tex]
⇒ [tex]6(17)[/tex]
Now , Total Number of family members and  friends which 24 students can invite , if every student invites x number of family members and  friends :
⇒ [tex]24(x)[/tex]
Equating both equations :
⇒ [tex]24x= 6(17)[/tex]
⇒ [tex]\frac{24x}{24}= \frac{6(17)}{24}[/tex]
⇒ [tex]x= \frac{6(17)}{24}[/tex]
⇒ [tex]x=4[/tex]
Therefore , Every student can invite 4 of family members and  friends  .
