Respuesta :
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
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
