Question

Ms. H 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. Write an equation that can be used to determine the number of people that she can bring to the zoo, including herself.

Answer 1

Let x be the maximum amount of tickets that Ms. H can buy.

Since each ticket costs $15.5, if she buys x tickets, she would spend 15.50x dollars.

Since she also have to pay for the parking, which costs $7, then the total amount of money that she spends buying x tickets and paying for parking, is:

$7+15.5x$

Since she has $100 to spend, this expression should be equal to $100 if she buys all the tickets that she can.

Therefore, the equation that can be used to determine the number x of people that she can bring to the zoo, is:

$7+15.5x=100$
