Aman selling computer parts realizes that when he sells 16 computer parts, his earning is $1700. when he sells 56 computer parts, his earning is $4300. what will the earning be if the man sells 30 computers parts?

We need to find the unit rate. To do so, divide the amount of money he makes by the number of parts sold. 1,700 / 16 = 106.25. So, if the man sells one computer part, he gets $106.25. To find the price of 30 parts, multiply 106.25 by 30. 106.25 * 30 = $3,187.50

The man will make $3,187.50 if he sells 30 parts.

y               = $2610

Step-by-step explanation:

This situation can be modeled with a straight line (that is, by a linear equation):

y = mx + b

The given data consists of two points on this line:  one is (16, $1700), the other (56, $4300).

If we move from the first point to the second, x increases by 40 and y increases by $2600.  Thus, the slope of this line is m = rise / run, or

m = $2600/40, or $65/part

Then the equation of this line, in point-slope format, is

y - 1700 = ($65/part)(x - 16)

Now, if the man sells 30 parts, the following equation gives his earnings:

y - $1700 = ($65/part)(30 - 16), or

y               = $1700 + ($65/part)(14 parts), or

y               = $2610
