The company discovered that it costs $61 to produce 3 calculators, $165 to produce 7 calculators and $385 to produce 12 calculators how much does it cost for 6 calculators

Hence, the cost for 6 calculators is:

                      $ 133

Let it follows the quadratic model.

i.e let

where a,b and c are real numbers.

where p(x) denotes the cost of x calculators.

Now, it is given that:

The company discovered that it costs $61 to produce 3 calculators.

i.e. when x=3  p(x)=61

Hence, we get:

and cost of 7 calculators is: $ 165

i.e.  

and cost of 12 calculators is:  $385

i.e.  

on subtracting equation (2) from (1) we get:

on dividing both side by 4 we get:

on subtracting equation (3) from equation (2) and dividing by 5 we get:

Now on subtracting equation (4) from (5) we get:

and by putting the value of a in equation (4) we get:

and now putting the value of a and b in equation (1) we get:

             Hence, the function that models the cost is:

Now, we are asked to find the cost of 6 calculators

when x=6 we have:

           The cost of 6 calculators is:

                       $ 133

sorry man i accidentally pressed yes my bad

step-by-step explanation:

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
