Lisa and her husband are each starting a saving plan. Lisa will initially set aside
$
125

and then add
$
50.85

every week to the savings. The amount
A

(in dollars) saved this way is given by the function
=
A
+
50.85
N
125

, where
N

is the number of weeks she has been saving.
Her husband will not set an initial amount aside but will add
$
75.65

to the savings every week. The amount
B

(in dollars) saved using this plan is given by the function
=
B
75.65
N

.
Let
T

be total amount (in dollars) saved using both plans combined. Write an equation relating
T

to
N

. Simplify your answer as much as possible.
