Answer to Question #278356 in Algebra for Kam

Question

A sandwich shop serves 4 ounces of meat and 3 ounces of cheese on each sandwich. After making sandwiches for an hour, the shop owner has used 91 combined ounces of meat and cheese.

Answer 1

Let the shop makes x sandwiches in that hour.

So number of ounces of meat the shop serves = 4x

And number of ounces of cheese the shop serves = 3x

Therefore the number of combined ounces of meat and cheese the shop serves = 4x+3x = 7x

According to the problem, 7x = 91

=> x = $\frac{91}{7} = 13$

Therefore the number of sandwiches the shop makes in that hour is 13
