Mae loses 3 points per wrong answer on a test. How does her score change with 7 wrong answers? $-21$

STEP 1

Assumptions
1. Mae loses 3 points for each wrong answer
2. She has 7 wrong answers

STEP 2

We need to find the total point loss due to the wrong answers. We can do this by multiplying the number of wrong answers by the points lost per wrong answer.
$Total\, point\, loss = Number\, of\, wrong\, answers \\times Points\, lost\, per\, wrong\, answer$

STEP 3

Now, plug in the given values for the number of wrong answers and points lost per wrong answer to calculate the total point loss.
$Total\, point\, loss = 7 \\times -3$

STEP 4

Calculate the total point loss.
$Total\, point\, loss = 7 \\times -3 = -21$
Mae's score changes by -21 points.
