Electronics kits and costs

A maker buys \(60\) sensors at \(x\) cents each and \(40\) cables at \(y\) cents each. The total cost is \(\$68\), and the sensors cost \(\$28\) more in total than the cables.

1. Form two equations in \(x\) and \(y\) to represent the information.
2. Solve the equations obtained in (a) to find the cost of one sensor and the cost of one cable.
3. The parts are packed into \(20\) identical kits, each containing \(3\) sensors and \(2\) cables. Find the cost per kit and the selling price per kit for a \(25\)% profit.
