ssignment (i Saved Help Bill's Roast Beef sells 6 times as many sandwiches as Pete's Deli. The difference between their sales is 350 sandwiches. How many sandwiches did each sell? \begin{tabular}{|l|l|l|} \hline Pete's sold & & sandwiches \\ \hline Bill's sold & & sandwiches \\ \hline \end{tabular}

Step 1 ：Let's denote the number of sandwiches Pete's Deli sold as x. According to the problem, Bill's Roast Beef sells 6 times as many sandwiches as Pete's Deli, so we can denote the number of sandwiches Bill's Roast Beef sold as 6x.

Step 2 ：The problem also states that the difference between their sales is 350 sandwiches. This gives us the equation \(6x - x = 350\).

Step 3 ：We can solve this equation to find the value of x, which represents the number of sandwiches sold by Pete's Deli. The solution to the equation is \(x = 70\). This means Pete's Deli sold 70 sandwiches.

Step 4 ：To find the number of sandwiches sold by Bill's Roast Beef, we multiply x by 6, which gives us 420 sandwiches.

Step 5 ：Final Answer: Pete's Deli sold \(\boxed{70}\) sandwiches and Bill's Roast Beef sold \(\boxed{420}\) sandwiches.
