Problema Solution

Sonia started the week at her sandwich shop with 15 3/4 pounds of cheese. At the end of the week, she had 5 1/4 pounds left. If she used 1/8 pound of cheese for each sandwich,how many sandwiches did she make with cheese that week?

Answer provided by our tutors

Let 'x' represent the number of sandwiches made.

(1/8)x = 15 3/4 - 5 1/4

(1/8)x = 10 2/4

(1/8)x = 21/2

x = (21/2)*(8/1)

x = 84 sandwiches

Sonia made 84 sandwiches.
