Caf$$ Tropical is a local restaurant specializing in tropical cuisine. Among its various

Hawaiian$-$themed menu item is the popular "Surprise$-$Me$-$Smoothie." The smoothies

are sold to regular customers at a price of $$6\mathrm{.}50$ per smoothie. The caf$$ typically

sells $40$ smoothies during breakfast. At this quantity, the smoothies cost the caf$$

$$2\mathrm{.}50$ each to make $-$ $$2\mathrm{.}00$ of the cost is variable and $$0\mathrm{.}50$ of the cost is fixed. The

restaurant is currently operating at $80\%$ capacity during the breakfast hour. The only

menu item offered during breakfast is the smoothie.

The caf$$ is considering accepting a special catering order for their "Surprise$-$Me$-$

Smoothie" from the Jazzagals before they depart for their a cappella competition.

The Jazzagals will need the smoothies ready for breakfast, one of the caf$\text{'}$s busiest

times. The Jazzagals need $30$ smoothies and would like a discounted price of $$4\mathrm{.}50$

per smoothie because of the quantity.

What will be the effect on operating income if Caf$$ Tropical accepts the special$-$

order?
