Question

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 maximum amount, to the nearest dollar, melinda will earn for each day of work, even if she serves no customers? $18 $25 $35 $40

Explanation:

Step1: Identify the linear - regression equation

The linear - regression equation is given as $y = 0.177x+25.36$.

Step2: Determine the value of $y$ when $x = 0$

When $x = 0$ (no customers served), we substitute $x = 0$ into the equation $y=0.177x + 25.36$.
$y=0.177\times0 + 25.36$.
$y = 25.36$.

Step3: Round to the nearest dollar

Rounding $25.36$ to the nearest dollar gives $y\approx25$.

Answer:

$25$
