Question

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

Answer 1

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.

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=(93)/(15.5)\\\\\Rightarrow\ x=6`

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

Answer 2

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
