Answer:
50 times
Explanation:
If 10 points is 50 gold, each point is worth 5 gold.
If you were to get 15 points at a time, you would get (15 × 5) 75 gold.
So, by dividing 3,700 / 75, we can figure out how many times 15 points goes into 3700 gold
3700 / 75 = 49.333
You can't get 15 points 0.33 times, so we have to round this number up to 50.
Once you have played 50 times, getting 15 points [and therefore 75 gold] each time, you will have earned 3700 gold.
