Question

Bill's Roast Beef sells 7 times as many sandwiches as Pete's Deli. The difference between their sales is 450 sandwiches. How many sandwiches did each sell?

Answer 1

bill sold 7525 sandwiches

pete sold 75 sandwiches

Explanation:

we say bills roast beef sells "b" sandwiches and pete sells "p" sandwiches.

set up system of equations

b=7p

b=450+p

7p=450+p

6p=450

p=75

so bill sold 75*7=525 sandwiches

pete sold 75 sandwiches
