The increase in allowance for option 1 each year can be calculated using the formula: Increase = Original Allowance * (Percentage Increase/100) = $10 * (7/100) = $0.70
The increase in allowance for option 2 each year is always $1.
Therefore, the difference in allowance between the two options after x number of years can be represented by the function:
Difference = (Increase Option 2 - Increase Option 1) * x = ($1 - $0.70) * x = $0.30 * x
