Incorrect. Let $\displaystyle{b}=\usepackage{cmbright}\Huge\$ the number of bags of basmati rice and let $\displaystyle{j}=\usepackage{cmbright}\Huge\$ the number of bags of jasmine rice. Then:

(A) $\displaystyle{b}+{j}={20}\usepackage{cmbright}\Huge\$

(B) $\displaystyle{5}{b}+{3}{j}={76}\usepackage{cmbright}\Huge\$

Solve (A) for j and substitute into (B). Simplify and solve for b.
