First, substract the total of points with the points he got from signing up, to find the points he got after playing
points after playing = 500 - 200
points after playing = 300

Second, divide the points after playing by the number of points per hour, to find how long Ming played
time = 300/20
time = 15

Ming played for 15 hours

Answer:

Ming has to play for 15 hours to earn 500 points.

Step-by-step explanation:

1. Make an equation: 200 + 20h = 500 pts

2. 500 - 200 = 300

3. 300 / 20 = 15

h = 15 hours
