Let x be number of hot dogs and y be number of steak sandwiches.
1. Start with the two equations:
x + y = 985 2.95x + 9.95y = 7343.75 2. Express
\( x \) in terms of
\( y \) using the first equation:
x = 985 - y 3. Substitute
\( x = 985 - y \) in the second equation:
2.95(985 - y) + 9.95y = 7343.75 4. Distribute
\( 2.95 \) in the equation:
2905.75 - 2.95y + 9.95y = 7343.75 5. Combine like terms:
2905.75 + 7y = 7343.75 6. Subtract 2905.75 from both sides of the equation:
7y = 4438 7. Divide both sides by 7:
y = 634 Hence, the number of steak sandwiches sold is
\( y = 634 \) .
