Basketball math questions

In kiwi sport we are learning how to play basketball. So far, we have learnt how to dribble the ball.
A) Chelsea was able to dribble the ball 58 times.
B) Liz could only  dribble half of what Chelsea can.
C) Semi could dribble the ball 7 times more than Chelsea.
D) Izac could dribble the ball 3 times more than Elizabeth.
Q) How many times can each person dribble the ball?

Chelsea =58
Elizabeth = 29
58 / 2 = 29
50/ 2 = 25
8 / 2 = 4
25 + 4 = 29

Semi = 406
58 x 7 = 406
50 x 7 = 350
08 x 7 = 56
350 + 56 = 406

Izac = 87
29 x 3 = 87
20 x 3 = 60
9 x 3 = 27
60 + 27 = 87
