Answer:
The contestant's final score is 20.
Step-by-step explanation:
Let's form this word problem into a written problem.
[tex]30 + 15 - 25[/tex]
Then, using addition and subtraction, we can determine how many points the contestant is left with. Firstly, add 30 and 15 together.
[tex]30 + 15 = 45[/tex]
Then, subtract 25 from 45.
[tex]45 - 25 = 20[/tex]
Thus, the contestant is left with 20 points.
30+15 - 25 = 45-25 = 20 points at the end
