Each week, heather's company has $5000 in fixed costs plus an additional $250 for each system produced. The company is able to p
Pepsi [2]

Answer:

Step-by-step explanation:

Step one:

Given data for Heather's company

Fixed cost = $5000

Additional cost = $250

in a week there are 168 hours

hence they will produce a total of 168/5= 33.6

=34 systems

the expression for the total cost can be modeled as

c=mn+f

where c=total cost

 m= the Additional cost

n= number of systems produced per hour

  h= the number of  systems produced per hour

   f= fixed cost

Step two:

c=mn+f

given that n=34, we can find the total cost as

c=250(34)+5000

c=8500+5000

c=13500

the total cost for each week is $13,500

elena55 [62]

If Monique used a total of 6 1/2 pounds of potatoes and each batch required 3/4 of a pound of potatoes, then you have to divide the total amount of pounds by an amount of pounds needed for one batch:

6\dfrac{1}{2}:\dfrac{3}{4}=\dfrac{13}{2}\cdot \dfrac{4}{3} =\dfrac{26}{3}=8\dfrac{2}{3}.
