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

Option D is correct

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

Explanation:

Using slope formula:

`\text{Slope} = (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} = (1420-1220)/(20-10)`

⇒
`\text{Slope} = (200)/(10) = 20`

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