Final answer:
The unit rate of $27 for 9 tickets is calculated by dividing the total cost by the number of tickets, yielding a unit price of $3 per ticket.
Step-by-step explanation:
The question is asking to express the ratio of $27 for 9 tickets in unit form. A unit rate is a ratio that compares two different quantities when one of the amounts is reduced to one unit. To calculate the unit price per ticket, you would divide the total cost by the number of tickets.
To find the unit price per ticket, we use the following calculation: $27 ÷ 9 tickets = $3 per ticket. So the unit rate is $3 per ticket. This means that each individual ticket costs $3.
Examples for Clarification
If you buy one ticket, it costs $3.
If you buy two tickets, it would cost $6 in total, as each is $3.
Understanding unit rates is useful when comparing costs and making informed decisions about purchases.
A unit rate is a ratio that compares two different quantities where the denominator is always 1 unit. It expresses the rate at which one quantity changes concerning another. For example, if the cost of 3 apples is $6, the unit rate is $2 per apple. It's often written in the form "per one" or "per unit." Unit rates are useful for making direct comparisons and understanding the relationship between different quantities, making them a common concept in various real-world scenarios, such as pricing, speed, and rates of work.
