Susan is putting money into a savings account. She starts with $750 in the savings account, and each week she adds $40.
2 answers:
To model this situation, we are going to use the standard linear function: 
.
1. Since S represent the total amount of money in the savings account,
. We also know that each week she adds $40 to her account, so the slope of our linear equation will be 
; therefore, 
. Since she started her account with $750, 
.
Lets replace those values in our linear function:
We can conclude that equation that models this situation is:
2. Now to find the total amount after 16 weeks, we just need to replace
with 16 in our equation and simplify:
We can conclude that the amount of money in her account after 16 weeks is $1390
