Question

Each day, Valerie charges her lunch account for her lunch. If the cost of 16 points

the lunch is $3, then by how rnuch has her lunch account been impacted
over a period of 15 days? (A charge on her account would mean a negative value)"

Answer 1

Valerie's lunch account is impacted by -$2.8125 over a period of 15 days, with each lunch costing $0.1875, as calculated from the given cost of 16 lunches for $3.

Step-by-step explanation:

To calculate the impact on Valerie's lunch account over a period of 15 days, we need to find out the daily charge and then multiply it by the number of days. We are told that 16 lunches cost $3, so to find the cost of one lunch, we divide $3 by 16, which gives us $0.1875 per lunch. Therefore, over 15 days, Valerie's account would be charged 15 times $0.1875.

Now, let's do the math: 15 days times $0.1875 per day equals $2.8125. Since a charge on her account means a negative impact, Valerie's lunch account has been impacted by -$2.8125 over 15 days.
