Question

According to the table, what is the increase in monthly pay for each hour of training?

Answer 1

For every 10hrs of training you have 200$ increase.
Then for each hour, it will be $20.

Answer 2

Answer:

Option D is correct

$20 is the increase in monthly pay for each hour of training

Step-by-step explanation:

Using slope formula:

$\text{Slope} = \frac{y_2-y_1}{x_2-x_1}$

As per the statement:

Let x represents the Hours of training and y represents the Monthly pay.

From the given table:

Let any two points i.e,

(10, 1220) and (20, 1420)

Since, increase in monthly pay for each hour of training is represented by slope.

then;

$\text{Slope} = \frac{1420-1220}{20-10}$

⇒$\text{Slope} = \frac{200}{10} = 20$

Therefore, $20 is the increase in monthly pay for each hour of training
