If you're asking for the model for the second problem (I didn't see any unsolved), here it is!
a. If we subtract 75 from 550 twice, we get 400, which is the third member to join. Subtract 75 from 400, we get $325, the fourth member to join.
b. It is not possible that a member would join for free if it was a large family. 75 does not fit into 550 evenly. You can prove this by solving the expression 550÷75.
c. The lowest amount that a member would pay to join is $25.00. It would be the 7th member.
Step-by-step explanation:
(x + 12)(x - 6)
x2 - 6x + 12x - 72
x2 + 6x - 72
