Set up a system and solve. At an ice cream parlor ice cream cones cost $1.10 and sundaes cost $2.35. One day the receipts for a total of 172 cones and sundaes were $294.20. How many cones were sold?
What is x + y = 172 1.10x + 2.35y = 294.20 1.10(172 - y) + 2.35y = 294.20 189.2 - 1.10y + 2.35y = 294.20 189.2 + 1.25 y = 294.20 y = 84 x = 88
