For this case we have to:
x: Variable that represents the number of times Henry visits the art museum.
If you pay 15 for parking and 25 for admission every time you go, we have:

Now, if you buy a membership at a net cost (it does not depend on the number of visits to the museum) of $ 110 and only pay $ 10 of parking, every time you attend the museum, we have:

Finally, the two equations that represent the situation are:

I hope this is the answer that u are looking for:)
(d)
,
, 
(e) 68, 82, 96
(d) note that the terms have a common ratio ( r )
r =
=
= 
to obtain any term in the sequence, multiply the previous term by 
75 ×
= 
×
= 
×
= 
(e) note that the terms have a common difference (d )
d = 26 - 12 = 40 - 26 = 54 - 40 = 14
to obtain any term in the sequence, add 14 to the previous term
54 + 14 = 68
68 + 14 = 82
82 + 14 = 96
