Question

ms. ordonez/ms. sparacello/ ms. brea 2.04 homework 1. alphonso is playing trivia with his brother. every time he gets a question correct, he is awarded 10 points and every time he gets a question incorrect, he loses 15 points. part a: alphonso got the first 6 questions incorrect. draw a model using a number line and determine his score after the first six questions. part b: the next set of five questions, alphonso got correct. draw a model using a number line to determine his score for this set of questions. part c: what was alphonsos score after the first 11 questions? show your work.

Explanation:

Step1: Calculate score for incorrect questions in Part A

Each incorrect question loses 15 points. For 6 incorrect questions, the score change is $- 15\times6=-90$.

Step2: Calculate score for correct questions in Part B

Each correct question gains 10 points. For 5 correct questions, the score change is $10\times5 = 50$.

Step3: Calculate total score after 11 questions

Add the scores from Part A and Part B. The total score is $-90 + 50=-40$.

Answer:

-40

Note: Drawing the number - line models would involve starting at 0, moving 15 units to the left 6 times for Part A (ending at - 90), and then from - 90 moving 10 units to the right 5 times to end at - 40 for the combined result. But the above is mainly focused on the numerical calculation part as required for the overall score.
