Answer:

Total amount = 7x + 25

Explanation:

Assuming that week can be denoted by a variable, in this case, x. Also assume that the total amount owned is denoted by the variable, y.

Note that $25 is the constant, meaning that that amount will not change. Norm would technically have at least $25 regardless of how much week passes.

The amount that changes per week is the addition of $7.

Set the equation:

Total amount = ($7 per week x amount of week(s)) + starting amount (constant).

Total amount = 7x + 25
