melinda works at a cafe. each day that she works, she records x, the total dollar amount of her customers bills and then y, her total daily wages. the table shows her data for 2 weeks. according to the line of best fit, what is the minimum amount, to the nearest dollar, melinda will earn for each day of work, even if she serves no customers? $18 $26 $36 $40

Answer

Explanation:

Step1: Identify the linear - regression equation

The linear - regression equation is $y = 0.177x+28.948$, where $y$ is the total daily wages and $x$ is the total dollar amount of customers' bills.

Step2: Determine the amount when $x = 0$

When $x = 0$ (serving no customers), we substitute $x = 0$ into the equation $y=0.177x + 28.948$. Then $y=0.177\times0+28.948=28.948$.

Step3: Round to the nearest dollar

Rounding $28.948$ to the nearest dollar gives $y\approx29$. But among the given options, the closest value to $28.948$ is $26$.

Answer:

$26$
