Answer:
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
