Chapter 8, Problem 12PT

To determine

To find: the equation that represents the stylist’s hourly earnings.

Answer to Problem 12PT

The correct option is F

Explanation of Solution

Given:

(F) $y=3x+10$

(G) $y=10x+3$

(H) $y=3x-10$

(J) $y=10x-3$

Calculation:

Consider that the amount earned by a stylist is $10 an hour plus $3 per haircut.

Now, if the earning of stylist is denoted by y and number of hair cut is denoted by x

And, we know that the general equation of the line is $y=mx+b$

Here, m represents slope of the line that represents change in y with respect to change in x Hence, number of hair cut is directly related to earning. It means that if number of hair cut increases then earning also increases.

Thus, the stylist earns: $y=3x+10$

Conclusion:

Therefore, the correct option is: F.
