Let \(N_{us}\) and \(N_c\) be the number of supermarkets located in US and Canada respectively
\(N_{us} = N_c + 22 \Rightarrow N_c = N_{us} - 22\)
We know that, \(N_{us} + N_c = 84\)
\(N_{us} + N_c = 84\)
\(N_{us} + N_{us} - 22 = 84\)
\(2N_{us} = 84+22 = 106\)
\(N_{us} = \frac{106}{2} = \textbf{53}\)
Hence, Answer is D
\(N_{us} = N_c + 22 \Rightarrow N_c = N_{us} - 22\)
We know that, \(N_{us} + N_c = 84\)
\(N_{us} + N_c = 84\)
\(N_{us} + N_{us} - 22 = 84\)
\(2N_{us} = 84+22 = 106\)
\(N_{us} = \frac{106}{2} = \textbf{53}\)
Hence, Answer is D
