The cost of one sundae is s and cost of one cone is c.
Mark buys 4 sundae and 3 cones for a total of $26. Cost of 4 sundae will be 4s, cost of 3 cones will be 3c. So we can set up the equation for Mark as:
Brian buys 5 sundae and 2 cones for a total of $29. Cost of 5 sundae will be 5s, cost of 2 cones will be 2c. So we can set up the equation for Brian as:
Using these two equations, the cost of one sundae and one cone can be calculated.
