Problema Solution
at an ice creme store, ice cream cones cost $1.10 and sundaes cost $2.35. One day, the receipts for a total of one hundred seventy-two cones and sundaes were $294.20. How many cones were sold?
Answer provided by our tutors
let
c = the number of cones sold then
172 - c = the number of sundaes sold
1.10*c + (172 - c)*2.35 = 294.20
by solving the equation we find
c = 88 cones sold
