Incorrect. You can model the scenario by creating a table:

	Total cost ($)	=	Price ($/pound)	*	Amount (pounds)
Walnuts	$\displaystyle{5.5}{x}\usepackage{cmbright}\Huge\$	=	5.50	*	$\displaystyle{x}\usepackage{cmbright}\Huge\$
Cashews	115.50	=	10.50	*	11
Total Mix	$\displaystyle{8.25}{\left({x}+{11}\right)}\usepackage{cmbright}\Huge\$	=	8.25	*	$\displaystyle{x}+{11}\usepackage{cmbright}\Huge\$

What equation can you create in order to solve this problem? Can you use the information in the Total Cost column?
