Answer:

The answer is "1500p".

Step-by-step explanation:

The given probability is = 7. so, it is  [tex]\frac{3}{12} \ = \frac{1}{4}[/tex]

It implies, that only if  [tex]120[/tex] people enjoy the sport, its school will gather

[tex]\ 120 \times \ 20\ p = \ 2400 \ p[/tex]

But, [tex]\frac{1}{4}[/tex]  its side will survive = 30 people, as well as the school would have to invest [tex]\ 30 \times \ 30p \ = \ 900p[/tex]

for lollipops  So, the school will collect = [tex]2400 - 900 = 1500p[/tex]
