Question

Katja's grade was lowered 3 points every time she was late

to class. This semester, Katja was late to class 6 times. What
number represents the change in Katja's grade?

Answer 1

Answer: -18

Explanation:

We know that Kayla’s grade was lowered every time she was late to class. Taking this into consideration, we multiply -3 and 6 (beacuse she was late to class 6 times; 3 is negative because her grade is decreasing) which results in -18.

The change is Katja’s grade is -18% or points.
