Ara joined the school basketball team four years ago. She has been playing 40 games every year. If her score for every game is 21 points, calculate the total number of points she has scored in the four years.
Fa go tlhokega bareki ba le 2 go rekisa koloi e le nngwe fela, go raya gore Jason o tla tlhoka bareki ba le 2*15=<<2*15=30>>30 go tla kwa showroom gore a kgone go rekisa dikoloi di le 15.
E re ka Jason a tlhoka go dira di-call tsa mogala di le 25 gore a dire gore motho a le mongwe a tle kwa showroom, go raya gore go bona bareki ba le 30, Jason o tshwanetse go dira di-call tsa mogala di le 25*30=<<25*30=750>>750. 
#### 750

Forty games every year translates to 40*4 = <<40*4=160>>160 games in four years.
If Ara scores 21 points in each game, she has scored 160*21 = <<21*160=3360>>3360 points
#### 3360
