Step 1 :Let x be the number of \(\$ 50\) bills and y be the number of \(\$ 10\) bills.
Step 2 :Set up equations: 50x + 10y = 1190 and x = y + 13.
Step 3 :Substitute the second equation into the first equation: 50(y + 13) + 10y = 1190.
Step 4 :Simplify and solve for y: 60y + 650 = 1190 \Rightarrow y = 9.
Step 5 :Substitute the value of y into the x = y + 13 equation: x = 9 + 13.
Step 6 :Calculate x: x = 22
