gavmur [86]

Answer: the amount by which her lunch account would have been impacted is $45

Step-by-step explanation:

Each day Valerie charges her lunch account for her lunch. If the cost of lunch is $3 then, it means that Valerie charges the lunch account with $3 daily. It means that in x days, she would have charged her lunch account with 3×x = $3x

If she charged her account for a period of 15 days, it means that x = 15. Therefore, the amount by which her lunch account would have been impacted is 3×15 = $45

<h3>How to solve the linear equation?</h3>

The linear equation is given as:
