The answer is Ms Hernandez can bring up to 6 people to the zoo.

x -  the number of people that she can bring to the zoo
The parking will cost $7: a = 7
Admission tickets will cost $15.50 per person: b = 15.50x
She can spend on parking and admission tickets $100:
a + b ≤ 100

a = 7
b = 15.50x

7 + 15.50x ≤ 100
15.50x ≤ 100 - 7
15.50x ≤ 93
x ≤ 93 / 15.50
x ≤ 6

Answer: The required equation will be :_

\(15.5x+7=100\), where x is the number of people that she can bring to the zoo, including herself .

The number of people that she can bring to the zoo, including herself = 6.

Step-by-step explanation:

Given: The total amount of money Ms.Hernandez has = $100

Let x be the number of people that she can bring to the zoo, including herself.

Then According to the question, the required equation will be :_

\(15.5x+7=100\\\Rightarrow\ 15.5x=100-7\\\Rightarrow15.5x=93\\\Rightarrow\ x=\frac{93}{15.5}\\\\\Rightarrow\ x=6\)

Hence, the number of people that she can bring to the zoo, including herself = 6.
