a. $\text{Profit}$	$=3.99-1.90$
	$=$2.09$

b. $\text{Percentage Profit}$	$= \dfrac{\text{Profit}}{\text{Cost of ingredients}}\times 100\%$
	$=\dfrac{2.09}{1.90}\times 100\%$
	$=110\%$

b. \(\text{Percentage Profit}\)	\(= \dfrac{\text{Profit}}{\text{Cost of ingredients}}\times 100\%\)
	\(=\dfrac{2.09}{1.90}\times 100\%\)
	\(=110\%\)
