Question

5. Naomi was watching a game show where

a contestant had 20 points and then had
5 turns where he scored - 10 points on
each turn. Then she stopped watching.
What was the contestant's score when
Naomi stopped watching the show?
A. -50
B. -30
C. 50
D. 70

Answer 1

C) 50

Explanation:

This is because -10 x 5 = -50 and if you have 20 points to start with, you just do 20-(-30)=20 and two minuses make a plus so it is 20 + 30 which is 50.
