Mrs Johnson has $110 to spend on parking will cost $12 and admission tickets will cost $140 per person including tax

Vaselesa [24]

<em>The answer is Ms Hernandez can bring up to 6 people to the zoo.</em>

<em />

<em>x - the number of people that she can bring to the zoo</em>

<em>The parking will cost $7: a = 7</em>

<em>Admission tickets will cost $15.50 per person: b = 15.50x</em>

<em>She can spend on parking and admission tickets $100:</em>

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
