You are given the following data:

Cost$\frac{}{b}=ar(C)=$$$2,400\mathrm{.}00$

$w=$$$20\mathrm{.}00$ per unit $of$ labor

$r=$$$20\mathrm{.}00$ per unit $of$ capital

These data are used to construct the isocost line $(C^1)$ in the diagram to the right.

Suppose the wage increases to $$60\mathrm{.}00$ but that the firm chooses to keep using the same amount of labor and capital to produce $200$ units of output.

Given this new set of factor prices $(w^{\text{'}}=$$$60\mathrm{.}00,r=$$$20\mathrm{.}00),$ how much have costs changed if the set of input choices remains at point $A?$$$2400.($Enter a numeric response using a real number rounded to two decimal places.$)$

Use the line drawing tool to draw a new isocost line showing an increase in $w$ to $$60\mathrm{.}00,$ given the firm chooses to keep using the same amount of labor and capital to produce $200$ units of output. Label this line $\text{'}{C}^2\text{'}.$

Carefully follow the instructions above, and only draw the required objects.
