Answer:
B. 10
Explanation:
We can solve this fast by adding the points from the stars and ships together, then subtracting that number from the total 500 points Mateo earnd.
So it would look like this:
180+270=450
500-450=50
So if Mateo scored 50 points from saving prisoners and save is worth 5 points each, we can do 50÷5=10.
