Problem solving Owen made 100 sandwiches which she sold for exactly $100. She sold

caviar sandwiches for $5.00 each, the bologna sandwiches for $2.00, and the liverwurst sandwiches for 10 cents. How many of each type of sandwich did she make?

C = number of caviar
B = number bologna
L = number of liverwurst

1st equation C + B + L = 100 2nd equation 10 cent = $1/10 5C + 2B + L/10 = 100

by elimination, first divide the 2nd equation by 10 and subtract to 1st equation so that we can eliminate L then we can get 49C + 19B = 900 ,simplifying divide the equation by 10 to becomes more realistic to the problem 4.9 C + 1.9 B = $90 (equation 3) to make exactly dollar by selling caviar & bologna she'll need to sell some multiple of 10 sandwiches C + B = 10 n the possible values of n must be multiple of 3 so lets try n = 3,6,9 and so on by solving further For n=3, B = 19
For n=6, B = 68
For n=9, B = 117 which is impossible

If B = 19, then C = 11 and L = 70.
If B = 68, then C = -8 which is impossible

The only possible answer 11 caviar 19 bologna 70 Liverwurst
