Equation relating to N is

50 + 106.3N

Step-by-step explanation:

Firstly, Equate the variables,

Total money saved by Donna is

A = 50 + 30.65N

where N is the number of weeks she has been saving

Total money saved by husband is

B = 75.65N

Total amount saved by Donna and her husband = A + B

=> 50 + 30.65N + 75.65N

=> 50 + 106.3N

From the question, total amount (in dollars) saved using both plans combined is T

therefore,

T = A + B

= 50 + 30.65N + 75.65N

= 50 + 106.3N
