Answer:
[tex]f(d)=-25d+3,500[/tex]
Step-by-step explanation:
Raul opened a savings account with $3,500.
Each week, Dale pays the dog sitter $25 from his saving account.
Let d be the number of weeks and f(d) be the function representing the amount of money in the account after Raul pays the dog sitter d weeks.
The amount of money in the Raul's account is decreasing each week by $25, then the slope of the linear function is [tex]m=-25[/tex]
Initially, at week d=0, Raul's account has $3,500, so b=3,500.
Write the function's expression in the form
[tex]f(d)=md+b[/tex]
Hence,
[tex]f(d)=-25d+3,500[/tex]
