What expression represents the amount of money Kyle has saved after x weeks?

To determine the correct expression representing the amount of money Kyle has saved after x weeks, we need to identify the pattern of savings implied in the context of the question.

The correct expression, 4(7x + 25), suggests that Kyle saves a fixed amount of money each week alongside a starting amount. In this case, "7x" indicates that for each week (x), Kyle saves $7. Multiplying by 4 suggests that there may be some additional element being accounted for, potentially another factor influencing the total savings (like perhaps the number of weeks he repeats some behavior or another aspect related to his savings strategy).

The addition of 25 likely represents a starting or initial amount that Kyle already had before he began saving. This balance increases over time as he continues to save $7 each week.

Overall, the expression neatly combines both his weekly savings and any initial savings, leading to a comprehensive total of the money he has after x weeks. This expression effectively captures a common scenario in savings problems where both a constant amount is saved regularly, and an initial balance contributes to the overall total.
