Ms. hernandez has $100 to spend on parking and admission to the zoo. the parking will cost $7,and admission tickets will cost $15.50 per person, including tax. write and solve an equation that can be used to determine the number of people that she can bring to the zoo, including herself

Given 
      $100 = total spend money for the parking and admission to the zoo
      $7 = cost for parking
      $15.50/person = admission tickets
Find x= number of people that she can bring to the zoo, including herself
Solution

100 = 15.50x+7

100 - 7 = 15.50x or ( 15.50x = 100 - 7)

100 - 7     15.50x
=
15.50       15.50

93      
=   x
15.50

6 = x 

The final answer is 6 people can Ms. Hernandez can bring in the zoo including herself.
