Respuesta :

We will solve as follows:

First, we will have that the expressions given in the problem are:

[tex]b_{m15}=176[/tex][tex]b_{m79}=b_{m15}+78[/tex][tex]s=69[/tex]

&:

[tex]n=b_{m15}+b_{m79}+s[/tex]

Now, we start by solving for bm79:

[tex]b_{m79}=176+78\Rightarrow b_{m79}=254[/tex]

Now, we determine the total number of people going to Central Park:

[tex]n=176+254+69\Rightarrow n=499[/tex]

So, there are 499 people going to Central Park.
