Mark is treating his family to ice cream. he buys 4 sundaes and 3 cones for a total of $26. brian also buys ice cream for his family. his total is $29 for purchasing 2 cones and 5 sundaes. determine the system of equations that can be used to find the cost of one sundae, s, and the cost of one cone, c. mark s + c = brian s + c = 5, 3, 29, 7, 55, 2 ,4, 26

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.
