Problema Solution
Albert's Corner Market sold large sandwiches at one price between $1.20 and $2.20. If the market made $32.81 on sandwiches in one day, how many did it sell?
Answer provided by our tutors
let x = the number of sandwiches sold, and x is integer
the money the market made is:
1.20x <= 32.82 divide both sides by 1.20
x <= 27.35
32.82 <= 2.20x
x >= 32.82/2.20
x>= 14.92
since x is integer we conclude: 15<= x <= 27.
they sold between 15 and 27 sandwiches.
