Final answer:
Darren and his brother will each have made 9 additional shots, for a tied score of 39 points.
Step-by-step explanation:
In order for Darren and his little brother to have a tied score in the game, they need to have an equal number of points. We can set up an equation to represent this:
12 + 3x = 30 + 1x
Where x represents the additional shots they each make. To solve for x, we can subtract 1x from both sides and subtract 12 from both sides:
2x = 18
Dividing both sides by 2 gives us:
x = 9
So, each brother will have made 9 additional shots. To find out the total points, we can substitute x = 9 into the equation:
Total points = 12 + 3(9) = 12 + 27 = 39
Therefore, Darren and his brother will have each made 9 shots, for a tied score of 39.
