Total cost ($) = Price ($/pound) * Amount (pounds)

Walnuts 60.50 = 5.50 * 11

Cashews $\displaystyle{12}{x}\usepackage{cmbright}\Huge\$ = 10.50 * $\displaystyle{x}\usepackage{cmbright}\Huge\$

Total Mix $\displaystyle{8.25}{\left({x}+{11}\right)}\usepackage{cmbright}\Huge\$ = 8.25 * $\displaystyle{x}+{11}\usepackage{cmbright}\Huge\$
