To find the solution, we set up two expressions: Expression for Singer A is 60 + 20x, and the expression for Singer B is 95 + 15x, where x is the number of hours.
We then set the two expressions equal to each other as 60 + 20x = 95 + 15x. This means that we are looking for the number of hours when the two singers will be charging the same amount.
To solve for x, simplify the equation by subtracting 15x from both sides, gives 5x = 35. Dividing by 5, gives x = 7 hours. This suggests that the two singers will charge the same amount of money after 7 hours of service.
