Question

you have $110 in your lunch account and plan to spend $2.75 each school day. Write and grapj a linear equation that represents the balance in your lunch account.

Answer 1

To represent the balance in your lunch account, you can use the equation: balance = initial amount - (daily expenditure * number of school days). In this case, the equation would be: balance = $110 - ($2.75 * x), where x represents the number of school days. This equation can be graphed as a straight line with a negative slope.

Step-by-step explanation:

To write the linear equation that represents the balance in your lunch account, we can use the following equation:

balance = initial amount - (daily expenditure * number of school days)

Given that you have $110 in your lunch account and plan to spend $2.75 each school day, the equation becomes:

balance = $110 - ($2.75 * x)

where x represents the number of school days.

Plotting this equation on a graph will result in a straight line with a negative slope, as the balance decreases with each school day.

Answer 2

The linear equation that represents the balance in your lunch account is y = 110 - 2.75x.

Step-by-step explanation:

To represent the balance in your lunch account, we can use a linear equation. Let x represent the number of school days elapsed. Since you plan to spend $2.75 each school day, the balance in your lunch account for each day can be calculated as 110 - 2.75x.

Therefore, the linear equation that represents the balance in your lunch account is y = 110 - 2.75x.

To graph this equation, we can plot points for different values of x and y, and then connect those points to create a line.
