Answer:

The answer to your question is y= 3x - 4.

Step-by-step explanation:

Plot the points (1,-1) and (2,2) and get your slope, in the case of slope-intercept form "m" using the rise/run method. You rise 3 units and run one unit to the right to get from (1,-1) to (2,2), so your slope is 3/1 or just simply 3. -4 is your y-intercept, or "b", because if you plot the two aforementioned points (1,-1) and (2,2) and make a line with them, your line meets the y-axis at the point (0, -4). Hope this helps!

A phone store employee earns a salary of $450 per week plus 10% comission on her weekly sales. A) What function rule models the
Gelneren [198K]

Answer:

A) E(w)=450+0.10w

B) $1200

Step-by-step explanation:

Let w represent employee's weekly sales and E(w) be total weekly earnings.

We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.

A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.

10% of weekly sales, w, would be \frac{10}{100}*w=0.10w

E(w)=450+0.10w

Therefore, the function E(w)=450+0.10w models the employee's weekly earnings.

B) To find the weekly sales in the week, when employee earned $570, we will substitute E(w)=570 in our formula and solve for w as:

570=450+0.10w

570-450=450-450+0.10w

120=0.10w

0.10w=120

\frac{0.10w}{0.10}=\frac{120}{0.10}

x=1200

Therefore, the amount of employee's weekly sales was $1200.
