Lizzy: Marcus scored 5 3-point goals and 10 2-point goals. If his team scored 70 points overall, what percentage of the team's total points did Marcus score?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find the total number of points Marcus scored through 3 - point goals: 5 goals * 3 points / goal = 15 points. Then find the total number of points he scored through 2 - point goals: 10 goals * 2 points / goal = 20 points. Then add those amounts to find the total number of points Marcus scored: 15 points + 20 points = 35 points. Finally, divide that number by the team's total number of points and multiply by 100% to find the percentage of points Marcus scored: 35 points / 70 points * 100% = 50%. Final answer: 50.
