Answer 1

After 8 days, he has spent
`\$8\cdot1.5=\$12`. Half his starting money would be
`\frac{\$30}2=\$15`. Hence, he has spent less than half his starting money.

If A and B are in a ration a:b then for each a of A there are b of B.

Hence for each 4 soccer players there is 1 volleyball player.
The number of soccer players is 4 times the number of volleyball players (the top left answer is correct).
If there are 4 volleyball players, there are thus 4*4=16 soccer players (and not 12)

If there are 16 soccer players, there are then 16/4=4 volleyball players, thus a total of 20 players: the third answer (bottom left) is wrong
