David is playing a video game. If he falls into a pit, he losses 125 points. If he collects coins, he will gain points. He has 400 points before her falls into 3 pits. After he collects a coin in each pit, his score is 175 points. How many points if each coin worth?

A coin is worth 50 points if collected

Step-by-step explanation:

Here, we want to calculate the worth of each coins in his video game;

Before falling into 3 pits, he had 400 points;

If he falls into a pit, 125 points is debited;

So the amount of points left after falling will be;

400-3(125) = 400-375 = 25

Now, after collecting a coin in each pit, his score is 175 points;

That means he has gained 175-25 = 150

Now kindly recall he fell into 3 pits and collected a point each in the three;

So this means, the worth of a coin is 150/3 = 50 points
