Miss hernandez has 100 to spend on a parking at admission to the zoo the parking will cost seven dollars and admission tickets will cost $15.50 per person including tax right at solve a equation that can be used to determine the number of people that she can't bring to the zoo including her self

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
