Answer:
26,250
Step-by-step explanation:
Ok, so lets find an equation for this situation. Lets say P is the total amount of spectators.
[tex]P=P\frac{3}{7} +15,000[/tex]
[tex]P[/tex] is equal to [tex]\frac{3}{7}[/tex] the total number of spectators in the covered area plus the 15,000 spectators in the open.
Solve for [tex]P[/tex]
[tex]P=P\frac{3}{7} +15,000\\P-P\frac{3}{7}=15,000\\7*\frac{4}{7}P=15,000*7\\4P=105,000\\P=26,250[/tex]
So, the total amount of spectators ([tex]P[/tex]) equals 26,250.
Answer Check
We know 15,000 people are in the open.
[tex]P-P\frac{3}{7} =15,000\\(26,250)-(26,250)\frac{3}{7}=15,000\\ 26,250-11,250=15,000\\15,000=15,000[/tex]
